so the disk is im guessing a speedometer?? the middle back has a wire and it spins or turns, the other lil thing is metal i was thinking maybe a sample tube of lipstick, lol i have no idea,
yes indeed is a lipstick tube i cleaned it up and the top has tangee on it, still the circle thing any ideas what it came from bike , motor cycle im racking my brain lol
If you remove the lens, you might be able to tell what it's for. Looks mechanical rather than electrical. I suspect it's for temperature, but, just my WAG.
