rear and side lamp style

[Bruce Parker (RIP)]

The white ones are for the front fenders (wings), one on each side.

On the back, both sides had those brackets with two holes each. On the left, there was one red tail lamp in the outer hole and the inner hole was left empty. On the right, there was a another red tail lamp in the outer hole and a red brake lamp in the inner hole.

The single red brake lamp worked off a pressure switch at the back of the master cylinder and could be isolated by a switch on the dash.

The pair of red tail lamps could be turned on with a switch on the dash, but from there the current went to a switch at the rear of the vehicle (a toggle switch on Fords marked 'red/white' and a dimmer switch on Chevs). Flip this switch one way and the current lit up the pair of red tail lamps. Switch it the other way and it lit up the 'white' lamp shining on the rear, white painted differential.

The lamp in your first pic is Ford or Chev (or any other Canadian military vehicle). Because of the round rear part it dates from 1943-45. The earlier ones had a large hex back.
