Britax is a UK warning light manufacturer that makes amber beacons and light bars for agricultural, commercial, and construction vehicles. The brand has led the vehicle beacon market since the 1970s, now trades as Britax PMG within the ECCO Safety Group, and sits in the mid-market tier of warning light products. This guide covers the beacon range, the mounting options, the ECE R65 approval classes, and how to choose the right Britax beacon for a UK farm vehicle.
Who Are Britax and What Do They Make
Britax is a British vehicle safety and lighting brand whose name comes from “British Accessories”, a business that began making automotive safety equipment in 1938. The early company produced seatbelts and motorcycle accessories before moving into mirrors, sunroofs, and aircraft interiors. The lighting side grew into a separate specialism focused on warning beacons and signalling.
The PMG part of the name traces to PMG Thorpe Ltd, a vehicle wiring and electrical business started in Yeadon, Leeds, in 1939. The two operations combined under the Britax PMG name, which now sits within the ECCO Safety Group, a multinational specialist in vehicle safety products. ECCO Britax has been the leading name in vehicle flashing beacons since the 1970s.
Britax makes warning beacons, light bars, work lights, mirrors, and electrical components. The agricultural relevance comes from the amber beacon and light bar range, which keeps slow-moving and wide farm vehicles visible to other road users. The brand supplies both original equipment to vehicle makers and replacement parts to the aftermarket.
Britax beacons cover halogen and LED technology, single beacons and multi-module light bars, and the full set of mounting options. The range meets the ECE R65 approval standard that governs amber warning lights for road use in the UK and Europe.

Britax Rotating and Halogen Beacons
Britax rotating beacons use an H1 halogen bulb to produce a continuous rotating amber warning. The rotating beacon is the established design and remains the lowest-cost route to a road-legal warning light on a farm vehicle.
The rotating mechanism spins a reflector or the bulb assembly around a fixed axis. The result is a sweeping amber beam that other road users read as a slow-moving or working vehicle. Replacement H1 bulbs are widely stocked and cheap, which keeps running costs low.
Two halogen beacon types cover the agricultural market.
Standard rotating beacons fit DIN pole, flexi, and bolt-on mounts on tractor and telehandler cab roofs. The H1 bulb draws around 55 watts on a 12 V or 24 V circuit.
OEM-pattern beacons replace the factory-fitted beacons on Case, New Holland, and other tractor brands. The Britax replacement matches the original base and connector for a direct swap.
Halogen rotating beacons draw more current and run hotter than LED, and the moving parts wear over time. They remain a sound choice for cost-sensitive replacement and for operators who prefer the familiar rotating pattern.

Britax LED Beacons
Britax LED beacons produce multiple flash patterns at a fraction of the current draw of halogen. The LED range is now the default choice for new fitment and for upgrades from halogen.
LED beacons replace the bulb and rotating motor with fixed LED arrays and electronic flash control. The benefits are lower current draw (typically 8 to 14 watts against 55 watts for halogen), no moving parts to wear, and a service life measured in tens of thousands of hours.
Three LED beacon features matter for farm use.
Selectable flash patterns let the operator choose rotating-simulation, single-flash, double-flash, or strobe. Multiple patterns suit different visibility needs on road and on site.
ECE R65 approval classes define visibility. Class 1 covers higher-intensity beacons for general road use. Class 2 covers beacons for vehicles that stop and work on or near live carriageways. Britax LED beacons cover both classes across the range.
Low-profile options suit cab roofs with overhead clearance limits, such as low barn doors and yard structures. The low-profile LED beacon stands well below the height of a traditional rotating beacon.

Britax Light Bars and Slimline Warning Systems
Britax light bars combine multiple LED modules into a single roof-mounted warning system. The light bar gives wider visibility than a single beacon and suits wide implements, contractor vehicles, and machinery working near traffic.
Two light bar formats cover agricultural use.
Mini and slimline light bars combine two or more LED beacon modules in a low-profile bar. These fit telehandlers, combines, and wide implement carriers where a single beacon gives too narrow a warning.
Full-width warning bars span the cab roof for the highest conspicuity on the widest machines. The modules synchronise their flash patterns across the bar.
Britax light bars carry ECE R65 approval and use sealed LED modules rated against dust and water ingress. The slimline profile reduces wind noise and clearance problems compared with a tall rotating beacon.

Britax Beacon Mounts
Britax beacons fit with DIN pole, flexi, magnetic, and bolt-on mounts. The mount choice depends on whether the beacon stays fitted permanently or moves between vehicles.
Four mount types cover the range.
DIN pole mounts fix the beacon to a standard DIN base on a rigid pole. This is the permanent fitment for tractor and telehandler cab roofs.
Flexi DIN mounts add a sprung or flexible joint that lets the beacon bend on contact with branches and barn doors. The flexi mount survives the low-clearance conditions of farm work.
Magnetic mounts hold the beacon to a steel surface for temporary use. The magnetic beacon moves between vehicles and suits contractors and occasional road work.
Bolt-on and three-bolt mounts fix the beacon directly to a bracket or panel for a low, secure fitment.

Where Britax Beacons Fit on UK Farm Vehicles
Britax beacons fit tractors, telehandlers, trailers, and slow-moving vehicles for road use. UK farmers and contractors fit Britax beacons to meet the visibility requirement when a farm vehicle travels on or works near public roads.
Three fitment situations apply.
Road-travel fitment covers tractors and self-propelled machinery moving between fields and farms on public roads. A flashing or rotating amber beacon warns other traffic of a slow-moving vehicle travelling below 25 mph.
Contractor and hire fitment suits machines that move between sites. A magnetic Britax beacon transfers between vehicles without permanent installation.
Wide-load and implement fitment covers vehicles carrying or towing wide equipment. A light bar or twin beacons give the wider warning that a single beacon cannot.

Where Britax Sits on Price and Quality
Britax sits in the mid-market tier of warning light products. The brand offers proven beacon designs and full ECE R65 approval at prices below the premium specialists.
Three price tiers describe the UK warning light market.
| Tier | Brands | Price index (Hella beacon = 100) |
|---|---|---|
| Budget | unbranded LED beacons | 25 to 45 |
| Mid-market | Britax, LED Autolamps, ECCO | 55 to 90 |
| Upper-mid | Hella, Vignal | 100 to 130 |
| Premium | specialist high-intensity LED | 140 to 200 |
A Britax LED beacon retails between £30 and £70 in the UK depending on flash patterns and mount. A halogen rotating beacon costs less, between £20 and £40, with cheap replacement bulbs but higher running cost. Britax beacons carry ECE R65 approval, sealed construction, and the backing of the ECCO group, which separates them from unbranded beacons of uncertain approval status.
Two situations argue for Britax over an unbranded beacon. The first is road use, where ECE R65 approval is the difference between a legal and an illegal warning light. The second is replacement on a vehicle already fitted with Britax or ECCO, where the base and connector match for a direct swap.
For the deeper beacon comparison, see the Beacon Buyer’s Guide: How to Choose the Right Warning Light and LED Beacons vs Halogen Beacons.
The Britax range covers the warning light requirement on UK farm vehicles, from a low-cost halogen rotating beacon to a multi-pattern LED light bar. Match the beacon to the visibility class the job needs, choose the mount that suits the vehicle, and the brand earns its mid-market place.
