The present invention relates to headlights of vehicles which are intended for use in difficult terrain. Such vehicles are mostly those for military use, such as tanks and halftracks which travel at considerable speed over difficult and irregular terrain.
Headlights of such vehicles are of rather complicated construction and comprise usually a metal housing the front of which is formed by a transparent lens-like wall seated in especially shaped, fluid and dust tight packings which latter are seated in appropriate seat grooves in the said casing. Furthermore, in view of the shocks and vibrations to which the headlights on such vehicles are exposed, special shock absorbing means have to be provided, being built into the lamp casing.
