Features
- Braking signal under blackout: the lamp lights when the driver brakes with the blackout circuit selected, so the next driver in the column sees the vehicle slowing while the service stop lamps stay dark.
- Low light output by design: a small lamp and a narrow light aperture keep the signal readable to the driver behind without lighting up the rear of the vehicle.
- Replaceable bulb: the light source is a standard bayonet bulb, so a failed bulb is changed by the crew or workshop instead of replacing the whole lamp.
- Ordered against NATO codification: the NSN identifies the item of supply, so the lamp is ordered and stocked against the same number whatever the source.
- Decontamination-ready finish: the paint resists chemical warfare agents, so the lamp goes through decontamination with the rest of the vehicle.
- Camouflage colour: the bronze-green housing matches the green base colour of the German three-colour camouflage scheme.
- One part for both sides: the same lamp fits the rear left or rear right position, so one stock item covers both corners of the vehicle.
- No connector to match: screw terminals and a grommeted cable entry take the existing vehicle wiring directly, without a specific plug.
What is a blackout stop lamp?
A blackout stop lamp is the brake signal a military vehicle shows when it drives with its service lights switched off. It lights only when the driver brakes, and only while the blackout circuit is selected, so the driver behind sees the vehicle slowing while the vehicle stays hard to observe from the ground or the air. In German service it is the Tarnbremsleuchte, part of the Tarnlicht system with the blackout driving lights, blackout tail lamps and convoy guidance cross. See our guide to VG standards.
The 1992 VG 72636 standards covered splash-proofed and watertight blackout stop lamps; the current German detail standard for the blackout stop and blackout rear lamp is VG 96945-5, edition 2023-04. This 54 mm lamp is a bulb-type blackout stop lamp with a red lens, one of our military blackout lights, supplied for fleet maintenance, obsolescence support and spares.

The 54 mm Lamp Keeps Bulb-Type Blackout Sets in Service
Many tactical vehicles in service still carry bulb-type blackout lighting. When a blackout stop lamp fails or is damaged, fitting the same 54 mm lamp keeps the brake signal the rest of the fleet shows, and keeps the existing 45 mm fixing holes, wiring and bulb spares. The vehicle itself needs no change.
Commercial part numbers are superseded and renumbered over a service life of twenty years or more. The NATO Stock Number stays with the item of supply, which is why fleet maintainers order this lamp against the NSN. Send us the NSN from your parts list, or the vehicle and lamp position, and we confirm the codified item before we quote.
Frequently Asked Questions
STANAG 4381 Edition 2, as published in the Czech defence standard ČOS 254001, asks for two blackout stop lamps on wheeled vehicles and at least one on tracked vehicles, at a recommended height of 380 to 1830 mm above the road, with the light showing through one circular opening. The 54 mm lamp mounts at the rear left or right, so one part serves both positions. Your vehicle’s own lighting drawing takes precedence. See our guide to STANAG 4381.
Yes. Send us the vehicle type, the lamp position and, if you have it, the manufacturer’s part number from the parts list, and we confirm the codified item, price and lead time. Where an NSN is given, we check it against the item before we quote, because one lamp type can exist in more than one codified version, for example with different sealing.
The 54 mm lamp gives visible red light, so the driver behind sees it with the naked eye. Where a column drives on night vision devices and must show no visible light, fit an infrared convoy brake light, which signals braking with 850 nm or 940 nm infrared LEDs that are seen through night vision devices.
