A lot of the FV pattern electrical equipment is still in use. For example the convoy light Robin mentions can be found on an Austin Champ from the early 50s, through to Ferrets, Saracens, Saladins, FV432s, CVRTs, Trailers, and they are still fitted to Land Rover XDs built in 1997/8. The FV pattern headlamps are still in use on CVRTs, FV432s and other vehicles, as is the horn found on Champs and Ferrets etc.
