Features
- Integrated blackout driving light – Combines low beam, high beam, and blackout driving light in a single housing, removing the need for a separate blackout lamp on the vehicle
- Warm white blackout output – The blackout function produces warm white illumination for low-signature driving without standard headlight output
- MIL-STD-810 and MIL-STD-461 compliant – Meets military environmental and electromagnetic compatibility standards for integration on armored and tactical platforms
- 10-32V DC wide input range – Covers 12V and 24V vehicle electrical systems from a single part number
- IP X7 sealed aluminum housing – Waterproof to 1 meter submersion with an aluminum body and polycarbonate lens for long-term durability
- MST bracket with shock and vibration absorption – The MST mounting bracket includes integrated shock and vibration absorption to maintain beam alignment under the mechanical loads of off-road and cross-country vehicle movement
- Multiple RAL color options – Available in over 13 military-standard colors including Olive Green, Black Olive, Matte Green, Earth Yellow, and Steel Blue
- ECE R149 certified – Meets European type approval for headlamp performance and beam pattern
The 420125 in a Military Headlamp System
The primary advantage of the 420125 over a separate headlamp and blackout lamp installation is integration. Military vehicles operating between overt and blackout modes typically require switching between two separate lamp systems. The 420125 handles both from a single housing with a single mounting point.
The MST bracket is available in two versions: MST1 at 60 degrees and MST2 at 30 degrees, accommodating the mounting angle differences across armored vehicle platforms. The bracket’s shock absorption system maintains headlamp aim through the vibration loads that cause conventional headlamp housings to shift zero over time.
For vehicles requiring a standalone blackout driving lamp without the combined headlamp function, the 420070 LED Blackout Driving Lamp covers that application. For the full range of STANAG 4381-compliant blackout lighting, see our blackout lights range.

Frequently Asked Questions
A combi headlamp combines multiple lighting functions in a single housing. The 420125 integrates low beam, high beam, and a blackout driving light into one unit, replacing what would otherwise require separate headlamp and blackout lamp installations on a military vehicle.
The MST1 bracket mounts at 60 degrees and the MST2 at 30 degrees. The correct bracket depends on the headlamp mounting angle on your specific vehicle platform. Both brackets include integrated shock and vibration absorption to maintain beam alignment under off-road operating conditions.
