I have an 06 ElectraGlide. I installed the Sunpie LED headlight & running lights. They’ve been working great for almost a year but now, I’m blowing the fuse. I’ve traced wires and don’t see anything that’s obvious. They’ll last a couple of weeks and then blow the fuse again.

 

If you're confident you have traced the headlight wiring and found no shorts, damaged connectors, loose pins, etc. then the culprit could very well be the headlight? I had this happen and found the culprit to be a cut in the wiring running from the fuse box to the light switch causing a short to ground.
