Cleaning up my K1 today and I thought there was water at the bottom of the headlight. Cibie H4 with a replaceable bulb. I pulled it off, removed the bulb and shook it out. A small strip of “U” shaped alloy! Where could it have come from?? The glass is bonded to the reflector and I don’t see any propose…… maybe a previous bulb had a reflector on a brace? Totally stumped. Anyone recognize this bit?
