So I got me some eBay special headlights and turn signals today. The signals and drl are the integrated led type. Well when I plugged them in I popped the park light fuse. So I replaced it with a 15 amp instead of a 10 since my led cab lights have also been wired in that circuit. They worked fine. So I try the turn signals. Right works great. The left side blew the fuse. So I put a 15 in it as well. When I turned it in it worked perfectly for about 5 seconds and stopped. Now the left signal doesn't work at all. The fuse is fine. When the headlights are on the left turn signal indicator in the dash stays on as well as the left park light and tail light signal. I tried putting a regular bulb in the front hut same thing happens. The right still works and the 4 way flashes work including the left side. Just the signal itself doesn't. The flasher makes an odd noise when the left signal is first turned on kinda like a weird squeak. So I pulled it out and the light is still on in the dash. Any ideas on this?? I'm excited to get it back together. Ridge runner just tuned my ecm for me and I haven't got to drive it yet. Please anyone help me if you have any ideas?

 

You do know you have to have a special blinker realy for LED lights ?

I have herd of these strange happenings before ..

 

The lights I bought had a box with them that I expected to be the load resistors for it. But the right side and 4 way flashers work fine. That's why I'm stumped on the left side especially with the wild behavior

 

Apparently I have a self healing truck. I took the left bulbs out to check them. Put back a 10 amp fuse in all the circuits. Boom. Works perfectly. No clue what happened.

 

Could have just been resistance in the fuse ? or in the connectors in the fuse box ..

 

I have no clue. I'm just glad it's fixed.
