Having problems with visor lights?

 

I know you were talking to OP but it's funny you should mention that. My middle cab light flickers usually when going down the highway. I've got to service the truck next week and figured on having a look at it. It's just the one light not the entire row of all 5.

 

It’s the harness. The one on passengers side always acts up first. I eliminated that on my Classic and the last one too. Replaced it with a harness from chrome shop. Regular female bullet type plugs. New LEDs with male bullet type plugs. Just be sure to pull the wires out from the Cab, cut both at a good spot. Not too short, leaving enough for future replacements. Good crimps, then push the crimps back into the Cab. Silicone the hole. Use 1/4” wire loom, zip ties to protect the new harness. No more problems.

 

I got 5 new ones sitting on the shelf. Was going to replace when I get the truck painted as the current ones are ratty looking. They are Grote brand. Flimsy plastic. Sort of disappointed.

 

I just re read the post. Only one working is the one on passengers side. Must have been the First visor light on Drivers side that usually has problems first. You can unplug it at the first light, and check for power. Running lights on fenders wiring is from the headlight harness. I’ve had to replace those wires too.
