Can someone ID this British light
 

John Bizal form Midwest Military is looking to ID some odds that he has found in his inventory. He has these lamps. I think I have seen them before but can't recall what their application is. I figured some of the British members would know.

British 1950's, Austin Champ and Humber one ton to name but two vehicles.

As Richard said. I think that this is the convoy light version with an even more restricted beam. In theory they are water proof and fairly robust.
