A telehandler lighting setup combines boom-mounted work lights, chassis and cab roof lights, an amber warning beacon, and a full set of road-legal lamps for public-road travel. A modern factory-built telehandler ships with 6 to 12 work lights, one or two beacons, and a complete road lighting kit. Older machines often run with 2 to 4 halogen work lights and need an LED upgrade to match the visibility of a current Loadall, MLT, or Scorpion. This guide covers every light fitted to a telescopic handler, where it goes, what it has to do, and how UK law treats the machine on the public road.
Why Telehandler Lighting Is Different From Tractor Lighting
A telehandler boom changes the lighting demand. The boom carries the load between 0 and 10 metres above the ground, and the operator needs visibility on the load itself, not just on the area around the machine. A tractor lights the field ahead. A telehandler lights the load above and the work zone alongside.
Three structural differences set a telehandler apart from a tractor for lighting purposes.
The first is the boom itself. The boom extends and retracts, lifts and lowers, and tilts the load through 90 degrees or more. Lights mounted on the chassis or cab roof can only follow the load up to a certain angle. Above that angle the load shadows the work. Boom-mounted lights solve the problem because they travel with the load.
The second is the side-on working pattern. A telehandler often loads or unloads from the side, parallel to a wall, trailer, or stack. The operator works from the cab looking sideways or upward, not just forward. Side and rear chassis lights become more important on a telehandler than on a tractor.
The third is yard use. Telehandlers spend more hours on hard-surface yards, near pedestrians, near other vehicles, and near buildings. Beacon visibility and reverse lighting carry more weight than on a tractor that mostly works in fields.

Boom Lights: Lighting the Load and the Lift Height
Boom lights mount on the boom itself and travel with the load. They are the single most important upgrade on any telehandler used after dark.
A factory-fitted boom carries 2 to 4 work lights. JCB Loadall fits 2 boom lights as standard on the AGRI and AGRI PRO models, with the option of a further 2. Manitou MLT models carry 2 to 4 depending on specification. Merlo Roto and Multifarmer models carry 4 boom lights as standard on the longer-reach machines.
Mount boom lights at the boom head, near the carriage, and angle them slightly downward so the beam covers the load and the area immediately below it. A 4,000 to 6,000 lumen LED flood per light covers a stack or trailer side at full lift. Use IP69K-rated lights because the boom takes the full force of pressure-washing during clean-down and the rear of the lamp lives in dust and debris from forks, buckets, and grabs.
Anti-vibration brackets matter on a boom. The boom whips through the air every time the load drops or the carriage tilts, and a hard-mounted lamp cracks its LED chips inside a season. Rubber-isolated brackets, sold by every reputable lamp brand, multiply lamp life by five to ten times.
Boom light wiring runs through a coiled cable along the boom or through an internal cable run inside the boom section. Manufacturer-fitted looms use the internal route. Aftermarket installations almost always use the external coiled cable. Use a heavy-duty Deutsch connector at the boom-to-chassis junction so the cable can be unplugged for boom service.
Aim the boom lights at the carriage and 1 to 2 metres beyond. Aiming further out throws light past the working zone and creates glare back to the cab through the boom-mounted load.
Chassis and Cab Roof Work Lights
Chassis and cab roof work lights light the area around the machine, including the wheels, the rear, the sides, and the working zone in front of the boom.
A complete telehandler chassis lighting setup uses six positions. The numbers below assume a single LED flood per position and give a typical lumen target.
| Position | Purpose | Lumen target |
|---|---|---|
| Front grille left | Forward and left forward | 3,000 to 5,000 |
| Front grille right | Forward and right forward | 3,000 to 5,000 |
| Cab roof front | Long-range forward | 5,000 to 8,000 |
| Cab roof rear | Reversing and rear monitoring | 4,000 to 6,000 |
| Side cab pillar | Side-on loading view | 3,000 to 5,000 |
| Rear chassis low | Hitch, drawbar, low rear view | 3,000 to 5,000 |
Total chassis output sits between 21,000 and 34,000 lumens for a complete setup, on top of the boom light output of 8,000 to 24,000 lumens. A full LED telehandler with boom lights, chassis lights, and cab roof lights runs between 30,000 and 60,000 lumens of working illumination.
Use a flood beam pattern for all six positions. A spot pattern wastes light beyond the work area on a telehandler because the operator rarely looks more than 30 metres ahead during loading work. Reserve combination beam patterns for cab roof front lights only, and only on machines that travel between yards or move at speed across long sites.

Beacons and Amber Warning Lights for Telehandlers
A telehandler used on a yard or near road traffic needs an amber beacon. The beacon warns pedestrians and other vehicle operators that a slow, wide, articulating machine is in the work area.
UK law requires an amber beacon on any agricultural vehicle travelling on a road at less than 25 mph, and a telehandler is classified as an agricultural motor vehicle when it has agricultural plates and tax. A telehandler on the public road at any speed below 25 mph must show an amber beacon. The same rule applies to plant-spec telehandlers used on public roads where they form part of construction or industrial traffic.
Three beacon types fit telehandlers.
A DIN pole beacon mounts on a 28 mm or 25 mm pole, fixed to the cab roof rear or the cab front roof rail. This is the standard factory fitment on JCB Loadall, Manitou MLT, and Merlo Roto machines. The beacon sits above the cab profile and projects 360 degrees of warning light.
A magnetic beacon clamps to any flat metal surface on the cab roof through its magnetic base. This is the right choice for a telehandler used on the road occasionally, where a permanent fitment would be over-specified. Magnetic beacons run from a coiled cable into the cab cigarette lighter socket or through a hard-wired feed to the auxiliary panel. See magnetic beacons for current options.
A flexi DIN beacon uses a sprung-spring mount that bends on impact with branches or low overhead structures. Telehandlers that work in or near orchards, polytunnels, or grain stores benefit from a flexi mount because rigid poles snap under contact. The beacon flexes back to vertical without damage to the pole or the beacon itself.
Choose an ECE R65 approved beacon for any road-going telehandler. ECE R65 sets the flash rate, the visible distance, and the flash pattern that count as legal warning. R10 EMC approval matters separately, especially on telehandlers built after 2010 with electronic engine management or telematics. A non-EMC beacon can cause warning lights on the dash, false fault codes, or interference with the load chart display. See ECE R65 Beacons for the full standard.
Telehandlers used near pedestrians benefit from a second beacon at the rear of the cab roof. A second amber beacon doubles the visibility from behind during reverse moves and means the warning continues if one beacon fails.
Road-Legal Lighting for Telehandlers Driven on UK Roads
A telehandler driven on the UK public road needs the same lighting as a slow-moving agricultural vehicle. The Road Vehicles Lighting Regulations 1989 set the requirement.
Seven lighting components are required for road-legal use.
| Component | Quantity | Position |
|---|---|---|
| Dipped-beam headlight | 2 | Front, symmetrical |
| Front position lamps (sidelights) | 2 | Front, symmetrical |
| Rear position lamps (taillights) | 2 | Rear, symmetrical |
| Brake lights | 2 | Rear, symmetrical |
| Direction indicators | 4 | Front and rear, both sides |
| Hazard warning system | n/a | Operates the indicators together |
| Number plate light | 1 | Illuminates the rear plate |
A telehandler over 2.1 metres wide also needs end outline marker lamps at the highest point of the front and rear, marking the full vehicle width. Most telehandlers exceed this width with the wheels at full track or with stabilisers extended for road travel.
Reflectors complete the road-legal kit. A telehandler needs amber side reflectors along its length if longer than 6 metres, and red rear triangular reflectors at the back. The triangular shape is mandatory for trailers, but for the telehandler itself a rectangular red reflector is sufficient.
Headlights on a telehandler must dip to the left for UK use. Continental machines imported from France or Germany may have headlights aimed for right-hand traffic, and these need adjustment or replacement before UK road use.
For the full UK lighting law, see Road Vehicles Lighting Regulations 1989 and Tractor Road Legal Lights.
Lighting by Manufacturer: JCB, Manitou, Merlo, Claas
Each major telehandler brand fits a different factory lighting kit. The differences matter when buying replacement parts or planning an upgrade.
JCB Loadall is the dominant telehandler brand in the UK. Current Loadall AGRI and AGRI PRO models ship with 4 to 8 LED work lights, 2 to 4 boom lights, a single DIN pole amber beacon, and a complete road-legal kit. Older Loadall models from the 526, 530, 535, and 541 series were halogen across the board, and these are the machines most commonly upgraded to LED. See JCB Telehandler and Loadall Lights for the full fitment guide.
Manitou MLT models fit a Manitou-branded LED package on current machines and a halogen package on machines built before 2018. The MLT 625, 730, 840, and 960 cover the agricultural range. Manitou uses a different boom cable routing from JCB, with an internal cable run on most boom sections.
Merlo Roto and Multifarmer models fit larger numbers of boom lights as standard, with 4 boom lights on the longer-reach machines. The Merlo Multifarmer doubles as a tractor and a telehandler, and its lighting kit includes everything needed for full road use plus PTO-driven implement work after dark.
Claas Scorpion telehandlers are built in partnership with Liebherr and share component design with Liebherr construction telehandlers. The Scorpion 732, 736, 741, 746, and 756 models use LED lighting throughout on the current series. Older Scorpion machines fitted halogen.
JLG, Genie, and other plant-focused telehandler brands appear on UK farms in smaller numbers. These machines often come with a plant-specification lighting kit that meets construction site requirements but may need additional rear road-lighting for full UK agricultural road use.
LED Upgrade Routes for Older Telehandlers
An older telehandler fitted with halogen work lights upgrades to LED with little effort and immediate benefit.
Three reasons drive the LED upgrade on a telehandler.
The first is power draw. A pair of 70-watt halogen work lights pull 12 amps from the alternator at full brightness. A pair of LED work lights at the same lumen output pull 4 to 5 amps. The difference matters because telehandlers often run multiple work lights, a beacon, and reversing lights at the same time, and an old alternator struggles to keep the battery charged under that load.
The second is vibration tolerance. Halogen filaments break under continuous high-frequency vibration. A boom-mounted halogen lamp typically lasts 200 to 400 hours of work before the filament fails. An LED lamp on the same mount lasts 10,000 to 30,000 hours.
The third is light output. A modern 60-watt LED work light delivers 5,000 to 6,000 lumens. A 70-watt halogen delivers 1,500 to 1,800 lumens. The LED produces three times the visible light at the same physical size and lower power draw.
EMC compliance matters for any LED upgrade on a telehandler built after 2010. Non-EMC LEDs interfere with the engine ECU, the load monitoring system, and any GPS or telematics fitted to the machine. Check for the R10 marking on every LED lamp before fitting it to a modern telehandler. For the full picture on EMC compliance, see Do LED Lights Interfere with GPS and Auto-Steer Systems.

Wiring and Switching for Added Telehandler Lights
Added lights wire through a relay back to the cab switch panel or auxiliary fuse panel. Wiring direct from the battery without a relay overloads the cab switch contacts and risks fire.
A standard relay-based wiring layout for added telehandler lights uses six components.
A 30-amp automotive relay sits in a sealed plastic housing, ideally inside the cab or under a sealed bonnet section. The relay carries the high-current feed from the battery to the lights.
A fused supply runs from the battery positive to the relay. A 30-amp blade fuse sized for the total light load sits within 300 mm of the battery. Use waterproof fuse holders on a telehandler because the chassis sees mud, water, and pressure-wash spray.
A switched trigger feed runs from a cab switch (or from the existing work light switch) to the relay coil. This low-current feed turns the relay on and off without carrying the full lamp load.
A heavy-gauge cable runs from the relay output to the lights. Use 4 mm² cable for loads up to 20 amps and 6 mm² for loads up to 30 amps. Run the cable through existing cable looms or use a separate split conduit to protect it from chafing.
Deutsch connectors at every junction prevent water ingress and corrosion. A telehandler that lives outdoors and gets pressure-washed weekly will corrode any standard automotive connector inside two years. Deutsch connectors hold up for the life of the machine.
A common ground point on the chassis completes the circuit. The ground point should be a bolted earth tag, bare metal under the bolt, with the cable terminated in a ring crimp.

What to Buy First If You Are Upgrading a Telehandler
A telehandler upgrade in priority order looks like this.
Boom lights come first. The boom lights deliver the biggest single visibility gain because they light the load, and the load is what the operator is paying attention to. Two LED boom lights at 5,000 lumens each transform an old machine.
Cab roof rear comes second. The cab roof rear light makes reversing safe in any work environment with traffic, pedestrians, or stacked product. A single 6,000 lumen LED is enough.
Beacon comes third if the machine does not already have one. An ECE R65 LED beacon on a magnetic or DIN pole mount adds the legal compliance for road work and the practical visibility for yard work.
Side cab pillar lights come fourth. Side lights pay back fastest on telehandlers that load trailers, lorries, or stacks parallel to the cab.
Cab roof front and front grille lights come last. These are the most expensive to add because of the wiring run, and the existing factory fitment usually does enough.
A complete LED upgrade for a 10-year-old telehandler runs between £400 and £900 in parts depending on lamp brand and quantity, plus 4 to 8 hours of fitting time. The result is a machine that lights its work as well as a current Loadall or MLT.
