Features
- One module per lamp function: tail and stop, signal, reversing, rear fog and blackout each have their own module and part number, so every rear lamp carries only the functions the vehicle needs.
- Service and blackout lighting in one layout: the blackout module is part of the same family as the service modules, so blackout capability is built into the rear lamp layout rather than added as a separate lamp.
- Replace one function, not the whole lamp: because each function is a separate module, a damaged or failed module can be ordered and exchanged on its own.
- Common spares across trucks and trailers: one module family covers the rear lighting of prime movers and trailers, which keeps the number of different spare parts in the fleet low.
- Solid-state LED: no filament to break under shock and vibration, and the stop signal lights instantly when the brakes are applied.
- Full unit alternative: where one housing is preferred, model 420065 combines tail, brake, indicator, convoy and blackout functions in a single rear light.
- Custom configurations: connector and cable arrangements can be adapted beyond the standard options to match the vehicle’s electrical system.
What are LED tail light modules?
LED tail light modules are single-function rear lamps that are combined to build the rear lighting of a military or specialist vehicle. Instead of one fixed rear light cluster, the vehicle builder or fleet selects the modules it needs: a rear position and stop lamp, a signal lamp, a reversing lamp, a rear fog lamp and a blackout lamp.
Each service module does one defined job. The rear position lamp shows the presence and width of the vehicle from behind, the stop lamp warns that the vehicle is braking, the reversing lamp lights the ground behind and warns that the vehicle is reversing, and the rear fog lamp makes the vehicle easier to see from behind in dense fog. The blackout module is used when the vehicle drives under blackout conditions, with the service lights switched off.
Integration and Configuration
Choose one module for each function the vehicle needs, then specify housing colour, protective gauge and connector or wiring option to match the vehicle. Check the mounting footprint against the dimension drawing on this page. If a single housing suits the vehicle better, the model 420065 full unit combines tail, brake, indicator, convoy and blackout functions in one rear light. For other rear lamp formats, see our full range of LED rear lights and the blackout lighting range.

One Rear Lamp Layout for Service and Blackout Driving
A military vehicle needs two kinds of rear lighting. In service driving, the vehicle behind must see where the vehicle is, when it brakes, when it turns and when it reverses. Under blackout, the service lamps go dark and only the blackout lights remain. On US military tactical vehicles this is set on the main light switch: the BO MARKER and BO DRIVE positions operate the blackout lights, and SER DRIVE operates the service lights.
With modules, both modes are part of one planned rear layout. The integrator places the service modules and the blackout module side by side and wires each to its own circuit, so switching between service and blackout driving needs no extra lamp. For the fleet, modularity means fewer different spare parts, faster repair after damage, and one family of rear lamps across trucks and trailers. The modules are rated to MIL-STD-810 environmental testing, as listed in the specifications.
Frequently Asked Questions
Five modules are available: 420068 Tail – Stop Light, 420059 Sign Light, 420056 Reverse Light, 420057 Fog Light and 420058 Blackout Light. Each covers one rear lamp function, so the rear lighting of the vehicle is built from the modules it needs.
Yes. The blackout module is wired to the vehicle’s blackout lighting circuit and the service modules to the service circuits. On a typical US military main light switch, the blackout lights operate in the BO MARKER and BO DRIVE positions and the service lights in SER DRIVE, so the driver selects one mode or the other.
Choose modules when the vehicle needs a specific combination of functions, when functions must be mounted in different positions on the vehicle, or when single functions must be replaced separately. Choose the model 420065 full unit when one housing with tail, brake, indicator, convoy, blackout brake and blackout position functions suits the vehicle better.
Yes. Five connector or cable configurations are available to match the vehicle’s electrical system, and custom solutions are also available.
The modules are listed as meeting IP68, MIL-STD-1275D, MIL-STD-461E and MIL-STD-810. MIL-STD-1275 sets the characteristics of 28 V DC military vehicle electrical systems, including voltage surges and spikes. MIL-STD-461 covers electromagnetic interference, so the lamps neither disturb nor are disturbed by radios and vehicle electronics. MIL-STD-810 covers environmental testing such as temperature, vibration and shock.
