Blackout light

In the military, they are intended for use when driving a convoy at night when it is necessary for the vehicles to maintain concealment by limiting their ability to be seen by the enemy.

Blackout driving lights are mounted on the driver's side of the vehicle, typically on the fender or grille.

They give off a diffused beam of white light that takes the place of regular headlights when driving under blackout conditions.

With the use of night vision goggles the effectiveness of the blackout driving light can be increased.

When the correct following distance of 180 to 60 feet is maintained the taillights appear as two red lights.
