How about out of a large flashlight? The ones that took the 6 volt batteries.I have the start of a headlight. It's based on a Star locomotive headlight. Main frame is a 4" pipe. Looking for a 4" reflector. I will probably have to turn one out of aluminum. Not sure about a light source. Any suggestions?
The ones I got are 2 5/8ths deep with a relatively Flat bottom for mounting a light socket.That might work. What is the depth?
