I have a problem with the top of my spotlight lenses getting smoke stains . They were replaced once already , only do do the same thing. I am in the process or converting all of my front lights to the old style , headlight and spotlights to Walker halogen sealed beams. The headlight is supposed to be a direct three prong plug in , but the spotlights need an adapter so I don't have to alter or cut the original wiring. Does anybody make these adapters? It would have the female end to plug onto my original wiring and on the other end of the two wires it would just have round terminals to hook on to the screw terminals on the spotlight bulbs.
