Yup - they're automotive fog lamps - just fine. Just dismantled it for the first time since 1961. It's sealed up tight, so there was some fine 1960 air in there
Clean as a whistle inside. GE bulb Made in USA. No wattage indicated on the bulb anywhere, and interestingly, labelled 13v. The transformer spits 12v out so all is fine.
Interesting combination of gaskets etc. to keep things water tight. The louvres are steel and keep the bulb in place, so they stay.
Going to mount very easily with a tiny L bracket mounted to the lower XS tree. The 2 6mm bungs for the old hydraulic line holders / brake light switch or whatever is normally bolted to the bottom tree of the XS should hold it well enough.
circa '62 Allis Chalmers. 4 1/2"; originally 6V; lamp and socket gutted; fabbed a mount for a 12V #9003 55/35watt halogen bulb; used a shaved storm door bottom sweep as a gasket. originally scored a pair of these and discovered one lens labled "driving" and the other "utility". i topped it off with a "rock guard", 'cause i havta deal with dirt roads getting in and out.

That is a very nice retrofit. How did you make the "rock guard"?
Harley fairing on my bates.
What is a good size for a round headlight?
