I put led turn signals and tail lights in my truck and am having issues. I put an EP29 flasher so they would work. When the dash lights are off and I turn on the left turn signal the dash lights flash with the turn signal and both tail lights flash too. When I turn on my dash lights the left turn signal on the dash is lit and will not work. I have no idea what is wrong, any help is much appreciated.

LED replacement bulbs in the taillights, or full-LED replacement lights that no longer use the stock sockets/bulb type?

If you did bulb replacements, the ones for the middle position (turn/brake) must be SRCK style. If you did not get these then stop before doing any more troubleshooting or thinking about it...and get the correct bulbs.

Next up, a lot of LED bulb replacements can cause problems like this, but usually not in GMT400's. Happens more with the cheapo ones.

They fully replaced the factory lights, I think it's something wrong with the wiring in just the front left turn signal.

Ahhh, OK. So the rear ones are going to plug directly into the existing wiring harness. How do those front replacements hook up? Do you have to tap wires, or do they have bulb-base style adapters that plug into your existing sockets? If they tap in, obviously check your wiring choices, probably mixed up some wires. If they plug into socket adapters, check the polarity.

They have two bulb bases and two what appear to be ballasts hooked into the back of the light

I just finished taking the turn signal apart, turns out I plugged one side in wrong. As of now everything seems to be working

Hey, by any chance could you post a night pic of those lit up? I like the look of those and am looking for a lighted picture on the truck.

That's cool. No rush. After this last rebuild my budget is crap until next fall.
