A large number of the lamps that attached to helmets date from the post war period. They are often boxed and have a red and black twisted cord. They are labeled as "LAMP SPOT ELECTRIC WITH HELMET CLIP". The below is I believe a wartime dated example and includes on the box "SHRAPNEL HELMET LAMP" and has a plain black cord connecting the lamp to the battery.
Very few period photos show the lamp being worn; though there is one of a Lewisham volunteer.
