Features
- Three lights in one housing: one lamp per rear corner replaces a cluster of separate lamps, with fewer cut-outs, brackets and cable entries to seal.
- Rear service functions: the specification lists tail, stop, signal, reverse and fog. The function of each of the three lights is confirmed when you order.
- Faster stop signal: LEDs reach full output without the warm-up of a filament. In a road safety study, drivers reacted on average 166 ms sooner to LED brake lamps than to standard incandescent ones.
- No filament to fail: solid-state LEDs cope with the shock and vibration of cross-country driving, and there are no bulbs to carry or change in the field.
- Lower electrical load: LED lamps draw less current than filament lamps, which leaves more of the vehicle’s power budget for radios, sensors and mission equipment.
- Less maintenance downtime: a long-life light source in a sealed housing keeps vehicles out of the workshop for lamp failures.
What is a 3-in-1 tail light?
A 3-in-1 tail light is a rear lamp that carries three lights in one housing, so a single unit does the work of separate tail, stop and indicator lamps at each rear corner. Model 420067 is a three-in-one rear lamp for military, industrial and off-road vehicles, with an aluminium body and a polycarbonate lens.
Its specification lists five rear functions: tail, stop, signal, reverse and fog. Each one has a different job, shown below. The lamp lists no blackout or convoy function, so it is a service lamp for normal driving. Model 420067 is one of our LED rear lights for military and specialist vehicles.
Red. Shows the presence and width of the vehicle from the rear.
Red. Tells the driver behind that the vehicle is braking.
Flashing. Shows that the driver intends to turn left or right.
White. Lights the road behind and warns that the vehicle is reversing.
Red. Makes the vehicle easier to see from the rear in dense fog.

One Lamp Position per Rear Corner
The rear of a military truck or trailer is crowded: tow hitch, steps, number plate, guards and often blackout lamps compete for space. Each separate lamp needs its own cut-out, bracket, cable entry and seal. Model 420067 gathers three lights into one aluminium housing, so each rear corner has one lamp to fit and wire.
The listed standards address the vehicle the lamp is fitted to. MIL-STD-1275D sets the characteristics of the 28 V DC supply in military vehicles, including surges and spikes. MIL-STD-461E controls electromagnetic interference, which matters next to radios and sensors. MIL-STD-810 sets environmental test methods for temperature, rain, sand and dust, vibration and shock.
Configuration and Ordering
Model 420067 is configured per order. Choose the housing colour from 13 options to match the vehicle’s paint or camouflage, whether you need the optional full 3 mm protective gauge, and one of nine connector or wiring options to suit the existing harness.
When you request a quotation, state the vehicle, its supply voltage, the function you need from each of the three lights, the existing rear lamp connector and the number of lamps. Ask for the pin assignment before you prepare the harness.
Frequently Asked Questions
Choose by the lighting modes the vehicle needs. Model 420067 lists service functions only. Our six-function LED rear light (Model 420065) and our tail lights with blackout function (Model 420066) have the same 224 mm by 114 mm face, but combine tail, brake and indicator with convoy, blackout brake and blackout position, and list no reverse or fog function. For a vehicle that must also drive under light discipline, choose one of those, or add dedicated military blackout lights.
Check the installation rules first, because they apply to the position of the lamp as well as the lamp itself. In Great Britain, for example, the Road Vehicles Lighting Regulations 1989 require a red rear fog lamp, a distance of 100 mm between its light-emitting surface and that of any stop lamp, no operation by the brakes and a circuit-closed tell-tale for the driver. In a compact three-light housing, that spacing must be checked. Model 420067 lists no ECE or DOT approval, so ask us which approvals apply before ordering for a road-registered vehicle.
It can. An LED signal draws much less current than a bulb, and a flasher unit that senses the load may read this as a failed lamp and flash fast. The usual fix is an LED-compatible electronic flasher, or load resistors where the flasher cannot be changed. See our guide to hyper flashing with LED lights.
The lamp lists MIL-STD-1275D and compatibility with MIL-STD-461E and MIL-STD-810, the last without a revision letter. Both 1275 and 461 have since been revised, and later revisions change limits and test methods. MIL-STD-810 is a set of tailored test methods, and no agency certifies compliance with it. If your contract calls up a later revision, such as MIL-STD-461G or MIL-STD-1275E, raise it at the enquiry stage and ask for the test reports and the methods applied.
