A Case IH tractor lighting system covers 6 active model ranges, 4 decades of production, and 3 generations of bulb technology. A 1985 Case International 1494 carries 4 sealed-beam lamps. A current Magnum AFS Connect 400 carries up to 16 LED work lamps with CAN-bus integration. The fitment, the bulb codes, the connectors, and the upgrade path differ across every era. Buying a replacement or upgrade lamp for any Case IH starts with the model name, the build year, and the original lighting specification. This guide covers the Farmall, Maxxum, Puma, Magnum, Steiger, and Quadtrac ranges, the standard fitment for each series, the LED upgrade options for classic and modern tractors, and the CNH Industrial parts crossover that connects Case IH to its sister brand New Holland.
How Case IH Tractor Lighting Works
A Case IH tractor lighting system is the network of lamps, wiring looms, switches, and electronic control modules fitted to a Case IH tractor for road, field, and yard use. The system splits into 5 functional categories common to every modern brand: front headlamps for road and forward visibility, work lamps for fieldwork, cab lights for interior comfort, beacons for road-legal warning, and rear clusters for tail, brake, indicator, and reverse functions.
Three lighting eras define the brand’s history. The classic era runs from 1985 (when J.I. Case absorbed International Harvester to create Case IH) through the late 1990s, covering the 94 series, 5100 Maxxum, 5200, 7100 Magnum, and 8900 Magnum. These tractors use sealed-beam or H4 halogen headlamps and modest factory work lamp fitment. The mid era runs from 2000 through 2012, covering the MX, MXM, MXU, JXU, and the early Puma, Maxxum, and Magnum ranges. These tractors use H4 and H7 halogen headlamps with optional HID upgrades and 4 to 8 factory work lamps. The modern era runs from 2012 to date, covering the current Farmall, Maxxum, Puma, Optum, Magnum, Steiger, and Quadtrac ranges. These tractors offer factory LED packages, CAN-bus integration, and up to 16 work lamps on the top Magnum and Steiger trims.
Case IH sits within CNH Industrial alongside New Holland Agriculture, Steyr, and Case Construction. CNH consolidates parts ranges where chassis platforms are shared, which means many modern Case IH lamps cross-reference directly with the New Holland equivalent. The first task before buying a replacement light is to confirm the series, the build year, and where applicable the CNH cross-reference part number.
Identifying Your Case IH Series
A Case IH series identifier appears on the bonnet decal, the chassis number plate (typically on the right-hand front frame rail or the cab pillar), and the operator’s manual. The series determines lighting fitment, wiring connector type, bulb specifications, and CAN-bus integration.
| Series family | Years | Common models | Lighting era |
|---|---|---|---|
| 94 series / 5100 Maxxum | 1985 to 1997 | 1494, 1594, 5120, 5130, 5140 | Sealed beam, H4 halogen |
| 7100 / 7200 Magnum | 1987 to 1998 | 7110, 7130, 7150, 7220, 7250 | Sealed beam, twin H4 halogen |
| 8900 Magnum | 1997 to 2002 | 8910, 8930, 8940, 8950 | Twin H4 halogen, optional roof bar |
| MX / MXC / MXU | 1997 to 2007 | MX135, MX180, MXU115, MXU135 | H4 / H7 halogen |
| MXM / Puma (early) | 2002 to 2010 | MXM120, MXM190, Puma 195, Puma 225 | H7 halogen, optional HID |
| Maxxum (current) | 2007 to present | Maxxum 115, 125, 140, 150 | Halogen with optional LED |
| Puma (current) | 2007 to present | Puma 165, 185, 200, 220, 240 | Halogen and factory LED options |
| Optum | 2014 to present | Optum 270, 300 CVX | Factory LED options |
| Magnum (current) | 2014 to present | Magnum 250, 280, 310, 340, 380, 400 | Full LED package option |
| Steiger / Quadtrac | 2010 to present | Steiger 370, 470, Quadtrac 500, 620 | Factory LED, up to 16 lamps |
| Farmall (current) | 2014 to present | Farmall 75A, 95A, 115U, 105U | Halogen with LED upgrade option |
Reading the Model Number
Modern Case IH model numbers state the engine power directly. Maxxum 140 = 140 hp; Puma 220 = 220 hp; Magnum 380 = 380 hp; Steiger 470 = 470 hp; Quadtrac 620 = 620 hp. Heritage Case IH model numbers run on a different scheme. The 94 series ran 1394, 1494, 1594; the 5100 Maxxum ran 5120, 5130, 5140 (last 2 digits indicate the power tier). A 7140 is a 7100-series Magnum at the 195 hp tier. The chassis plate confirms build year and original specification.
CNH Industrial Cross-Reference
A modern Case IH built on a shared CNH platform shares many lamp parts with the New Holland equivalent. The Case IH Maxxum and the New Holland T6 share the chassis, cab, and lighting modules. The Case IH Puma and the New Holland T7 share work lamp positions and connectors. The Case IH Magnum and the New Holland T8 share the rear cluster and roof bar fitment. Where an OEM Case IH part is unavailable or expensive, an OEM New Holland cross-reference often slots in directly. The New Holland tractor lights guide covers the equivalent fitment.
Heritage Identification Checks
A classic Case IH 1494, 1594, or 5140 needs careful verification because production ran for several years with detail changes. The bonnet shape, the dashboard layout, the cab roof line, and the headlamp surround design all narrow the year. The chassis plate confirms it. For lighting purposes, the key questions are: sealed beam or H4 halogen on the headlamps, single rear tail bulb or twin tail/brake, presence or absence of cab roof work lamps, factory beacon mount or retro-fit pole.
Case IH Headlamps by Series
A Case IH headlamp sits in the front grille, bonnet face, or fender. Bulb specification, lamp size, and mounting method vary by series.
| Series | Headlamp type | Bulb code | LED upgrade option |
|---|---|---|---|
| 94 series, 5100 Maxxum | Round sealed beam (177 mm) | Sealed unit | 7-inch LED sealed beam replacement |
| 7100 / 7200 Magnum | Twin sealed beam or H4 | Sealed / H4 60/55W | LED sealed beam or H4 plug-in |
| 8900 Magnum | Twin H4 in moulded housing | H4 60/55W | LED H4 plug-in |
| MX / MXC / MXU | Twin H4 or H7 | H4 / H7 55W | LED H4 or H7 plug-in |
| MXM / early Puma | Twin H7 high/low | H7 55W | LED H7 plug-in |
| Maxxum (current) | Halogen H7 or factory LED | H7 / OEM LED | LED H7 plug-in or full LED unit |
| Puma (current) | Halogen H7 or factory LED | H7 / OEM LED | Full LED unit available |
| Magnum / Steiger / Quadtrac | Factory LED standard or option | OEM LED | Already LED on top spec |
| Farmall | Halogen H4 or H7 | H4 / H7 | LED plug-in |
Case IH 1494, 1594, 5140 Headlamps
A classic Case IH 94-series or early Maxxum carries round sealed-beam headlamps mounted on the bonnet sides through a chrome bezel. The sealed beam unit replaces as a complete glass envelope. Modern 7-inch LED sealed-beam replacements drop into the original bezel without modification, producing 3 to 5 times the effective lumen output of the original incandescent sealed beam at one third of the current draw. A sealed-beam-to-LED upgrade is the single most cost-effective lighting improvement on a working classic Case IH.
MX, MXM, MXU, and Early Puma Headlamps
Mid-era Case IH tractors moved to H4 then H7 halogen headlamps in plastic or metal housings. The H4 bulb is a 60/55W dual-filament unit; the H7 bulb is a 55W single-filament unit. Replacement is a 5-minute job: release the bulb retainer clip, withdraw the bulb without touching the glass envelope, fit the new bulb, refit the clip. LED H4 and H7 plug-in replacements drop into the same housing for a no-rewire upgrade. The full halogen-to-LED process sits in the halogen to LED upgrade guide.
Modern Maxxum, Puma, Magnum Headlamps
Current Case IH tractors fit halogen or factory LED headlamps depending on trim. The factory LED option produces 5,000 to 8,000 lumens per side at low current draw with no warm-up. Replacement of a factory LED unit is a complete-assembly swap because the lamp integrates with the CAN-bus. Aftermarket full LED replacement units that match the Case IH connector and beam pattern offer a lower-cost alternative when the OEM part is back-ordered.
Steiger and Quadtrac Headlamps
A Steiger or Quadtrac articulated tractor carries up to 4 forward-facing lamps in a wide grille and bonnet array. The factory LED package produces 6,000 to 10,000 lumens combined at the front. Replacement comes through the CNH parts network or as a direct-fit aftermarket LED unit.
For the broader headlamp context, see the tractor headlights guide.
Case IH Work Lights by Series
A Case IH work light is a high-output lamp aimed at the working area around the tractor. Standard fitment runs from 0 lamps on a base classic to 16 on a fully optioned Magnum or Steiger.
Classic 94 and Maxxum Work Lights
A classic 1494, 1594, 5140, or 5150 typically left the factory with 0 to 2 work lamps. Where fitted, the work lamp was a single 55W H3 halogen unit on the cab roof front edge. Most working classic Case IHs have had work lamps retro-fitted at some point. The standard retro-fit is a pair of 55W H3 halogen units on the cab roof corners or, where no cab is fitted, on the safety frame uprights. LED upgrade replaces each 55W H3 with an LED unit at the same 4-bolt mounting pattern.
MX, MXM, and Early Puma Work Lights
MX, MXC, MXM, MXU, and early Puma series Case IH tractors increased standard fitment to 4 to 6 work lamps. Position is cab roof front and rear corners with optional A-pillar lamps. Bulb codes are typically 55W H3 in heritage units and 70W H9 in later units. The work lamp loom is fused at the cab roof junction box.
Modern Puma, Magnum, and Steiger Work Lights
Modern Case IH tractors offer work lamp packages with up to 16 factory LED lamps on a Magnum 380 or Steiger 470 specified with the full Surround Vision package. Each LED lamp produces 2,500 to 4,500 lumens at draws of 35W to 60W. Replacement is a full-unit swap because the lamps integrate with the CAN-bus to report status to the dashboard.
Common Work Lamp Mounting Positions
A Case IH work lamp fits in 7 standard positions, in order of factory and aftermarket popularity.
- Cab roof front corners (2 lamps)
- Cab roof rear corners (2 lamps)
- Cab roof apex bar (2 to 4 lamps)
- A-pillar (1 each side)
- Front grille bonnet edge (2 lamps)
- Rear cab pillar facing rear (2 lamps)
- Fender top facing forward (2 lamps, Magnum and Steiger)
The fitment decision follows the task. Ploughing at night needs front and side coverage. Round baling at dusk needs rear and high-angle coverage. Loader work needs A-pillar and front coverage. Combine harvester support work needs a combination of all 7. For the wider work-light selection process, see the tractor work lights guide.
Case IH Cab Lights and Beacons
A Case IH cab light is an interior lamp inside the operator cab. A Case IH beacon is the amber rotating or flashing warning light fitted to the cab roof for UK road use.
Interior Cab Lights
Standard interior fitment on heritage Case IH tractors is 1 dome lamp in the cab roof centre and 1 spot/reading lamp above the operator. Bulb codes vary: classic tractors (94 series, 5100 Maxxum, MX) use festoon or BA15s bulbs at 5 to 10W; modern Magnum and Steiger tractors use LED units integrated into the cab roof headlining. Replacement on heritage tractors is a quick festoon swap. Replacement on modern tractors requires a complete assembly through the CNH dealer.
Roof Beacons
A Case IH operating on UK roads needs an amber beacon on the cab roof. The beacon mounts through a DIN pole, a flexi-DIN pole, or a magnetic base. For the regulatory framework, see ECE R65 beacons. For portable options, see magnetic beacons. Most classic and mid-era Case IHs need a retro-fit beacon mount because factory beacon fitment was uncommon before the MXM series. Modern Case IH tractors from the current Maxxum onwards carry a factory DIN socket on the cab roof.
Roof-Mounted Warning Bars
A Case IH operating as a wide vehicle, a slow-moving haulage tractor, or a contractor escort needs more than a single beacon. A roof-mounted warning bar (300 to 1,200 mm wide) gives 360-degree visibility with multiple LED modules. The bar mounts on a flexi-DIN pole or directly to the cab roof through 2 to 4 bolts. Roof-mount warning bars are the standard fit on modern Case IH contractor tractors operating on UK roads daily.
Case IH Rear Lights and Tail Lamps
A Case IH rear light is a tail lamp, indicator, brake light, or number plate light fitted to the rear of the tractor for UK road use. The fitment evolves through the brand history.
Classic 94 and Maxxum Rear Lights
A classic 1494, 1594, or 5140 typically carries a single rear tail lamp on each rear fender. The lamp is a basic combination of tail/brake bulbs (P21W or P21/5W) and indicator (PY21W). Some early models carry no factory indicator at all, requiring retro-fit indicators on each rear corner for road-legal use. Replacement bulbs are universal and available as halogen or LED.
MX, MXM, and Early Puma Rear Lights
Mid-era Case IH tractors fit a more complete rear cluster with separate tail, brake, indicator, and number plate functions. Bulb codes match the heritage range with the addition of W5W for the number plate light. Some MXC and MXM specifications added a rear fog lamp on the right-hand fender.
Modern Maxxum, Puma, Magnum, Steiger Rear Lights
Modern Case IH tractors fit full LED rear clusters integrated into the cab rear panel or fender. The cluster combines tail, brake, indicator, fog, and reverse functions into a single sealed unit. Replacement is a full-cluster swap. Aftermarket LED rear clusters that match the Case IH connector pattern provide a cheaper alternative when the OEM cluster fails.
For the universal rear lighting context, see tractor tail lights and rear brake light bulbs.
LED Upgrades for Case IH Tractors
A Case IH LED upgrade replaces sealed-beam, halogen, or HID lamps with LED equivalents. The upgrade case is strongest on classic and mid-era Case IHs because the original units fail more often and produce far less light than a modern LED at the same form factor.
Classic 94 and Maxxum LED Upgrade
The simplest upgrade path on a 1494, 1594, 5130, or 5140: a 7-inch LED sealed-beam replacement headlamp into the original bezel, plus LED bulbs in the existing fender tail lamps. Cost: £40 to £120 per headlamp, £8 to £20 per tail bulb. Time per lamp: 5 to 15 minutes. The visual improvement on a classic tractor used at dusk or in early-morning yard work is significant. For the full process and cost-benefit detail, see the halogen to LED upgrade guide.
MX, MXM, MXU LED Upgrade
These tractors benefit most from a full-unit LED replacement on the work lamps because the original halogen units run hot and fail under PTO vibration. LED work lamp units bolt to the same 4-bolt pattern, draw 60% to 75% less current, and produce 4 to 6 times the effective lumen output. Headlamp LED upgrade is also straightforward: H4 or H7 LED bulbs or full LED headlamp units fit the existing housings.
Modern Maxxum, Puma, Magnum LED Upgrade
Modern Case IH tractors specified with halogen factory packages benefit from a work lamp LED upgrade for the same reasons as mid-era tractors. Modern Case IH tractors with factory LED packages need OEM-spec or CAN-bus-compatible aftermarket replacements when a lamp fails.
CAN-Bus Considerations
Case IH CAN-bus systems on tractors built since 2010 monitor lamp current draw to detect bulb failures. An LED draws less current than the halogen it replaces, which the CAN-bus interprets as “bulb out”. The fix is a CAN-bus-compatible LED bulb (with internal current emulation), an external load resistor in parallel with each LED, or an electronic flasher relay for indicator LEDs. Without these fixes, the dashboard shows a fault and the indicator hyperflashes.
CNH Industrial Cross-Reference for Case IH Lights
A Case IH replacement lamp often crosses directly with a New Holland equivalent because both brands sit within CNH Industrial. The crossover is most useful on modern shared platforms.
| Case IH model | Shared platform | New Holland equivalent | Lamp parts shared |
|---|---|---|---|
| Maxxum 115 to 150 | T6 platform | T6.140 to T6.180 | Headlamps, work lamps, rear cluster |
| Puma 165 to 240 | T7 platform | T7.190 to T7.270 | Headlamps, work lamps, rear cluster, beacon mount |
| Optum 270 / 300 | T7 HD platform | T7.290 / T7.315 HD | Most lamp parts |
| Magnum 250 to 380 | T8 platform | T8.320 to T8.435 | Work lamps, rear cluster |
| Steiger / Quadtrac | T9 platform | T9.435 to T9.700 | Most lamp parts |
When the Case IH part is unavailable or back-ordered, the New Holland equivalent often shows in stock at the same or lower price. The lamp itself is the same physical part with a different decal.
OEM vs Aftermarket Case IH Lights
A Case IH replacement lamp comes from one of 3 sources: OEM through the Case IH dealer, OEM CNH cross-reference where shared chassis applies, or aftermarket through an independent supplier. Each has a clear best-fit case.
| Factor | OEM Case IH | OEM CNH cross-ref | Aftermarket |
|---|---|---|---|
| Cost | High | High | Low to medium |
| Lead time | 1 to 14 days | 1 to 14 days | 1 to 5 days |
| Connector match | Exact | Usually exact | Usually exact |
| CAN-bus compatibility | Built-in | Built-in | Needs to be specified |
| Warranty | Full Case IH warranty | CNH group warranty | Aftermarket 1 to 5 years |
| Heritage availability | Variable | Limited | Strong |
When OEM Case IH Wins
A modern Case IH still under factory warranty needs OEM lamps. A high-spec contractor Magnum or Steiger where downtime is expensive justifies OEM on reliability grounds. A modern Magnum AFS Connect with multiple CAN-bus integration points has fewer issues with OEM than with low-cost aftermarket.
When CNH Cross-Reference Wins
A modern Case IH built on a shared T6, T7, T8, or T9 platform often has a New Holland OEM lamp at equivalent or lower price than the Case IH item. The lamp is the same physical part. The New Holland parts catalogue sometimes shows availability when the Case IH catalogue lists “out of stock”.
When Aftermarket Wins
A classic 94, Maxxum, MX, MXC, MXM, or MXU saves 50% to 80% on lamp parts by going aftermarket without meaningful downside. Heritage Case IH parts are increasingly hard to find through the official parts network, and reputable aftermarket suppliers stock equivalents for every major lamp position. LED upgrade work usually goes aftermarket because OEM LED upgrade kits never existed for classics and mid-era tractors.
