    Headlight question. On the 27 Hotrod we have a faulty headlight. It’s on then it’s not. If I wiggle the quick release connector it has, I can tell there’s an issue because the light flickers. I am not sure how to tell if it’s in the ‘male’ end or the ‘female’ end. And what are these called and can I get replacements? I did rewire most of this light about two years ago to switch to halogens, maybe I did something to the connector. Or maybe it’s always been faulty. Thanks

    Does it have original 1927 headlights, with the bulb, and the tube with the contacts, and the double contact on the end of the wire? If so, it might be a loose wire in the contact on the end of the wire, or it might be a worn out contact in the tube, or it could be a loose ground of the headlight ***embly, or the tube, etc. Or the bulb is flaky

    but if it's something else, it would really help to know what exactly you have.

    Are you talking about a three wire seal beam connector? Or an H4 modern halogen connector? Or?

    First, be sure the light has a good ground, as Jim suggested.

    Photo would help. Often looking close at a plug,can see one thing about it,by the color of br*** plug parts= dark or black is burned,very shiny is good. Also heat,with nit on an working,turn off an unplug an feel{with out burning your self,to see if it is hot an were it is hot. Can get idea of what needs fixing.

    If you have a original headlamp switch they may not handle the hi current needed for Halogen headlamps. The switch internal contacts could be burned from the current flow. Then you should install relays on both lamps , the switch will cool down and your lamps will be brighter .
