Ok here is the back of the tail lights that I have. Problems: No running lights or license plate lights. Fast blinker, top of driver side no lights. Took the lights off and saw those exact boxes, 4 of them two on each side. 3 of them have capacitors/diodes/resistors they are blue with wires on them rolling around not connected to anything inside. Does any companies sell these or should I attempt to repair them or buy new ones? I love the look of them but I need functionality before I get tickets.

 

I've never heard of those LEDs. Not sure what your issue is if your tag lights and running lights are also not working.

Resistors will fix the hyper flashing, but your other issues could be caused by the exact LEDs you're using.

Where did you get them and what did you pay? There's more cheap junk out there than there is quality stuff.

 

They came on the truck. I've been trying to research them and the boxes on them but I can't find anything related to them.

 

So I take it the PO installed them? Personally, I'd get rid of them and go with a trusted source / brand.

Still doesn't make sense why your tab lights wouldn't work. Did someone hack into the wiring?

 

I'd love to take it to the place that installed them but I don't know who that is. What brands would you recommend for led tails?
I'm going to crawl around under it tonight and see what I can find with the wiring, im hoping its just a bad ground or broken wires..

 

I'd personally recommend a high end led bulb with the stock housing. I take it the stock housing didn't come with the truck though, right?

 

If I was in desperate need of new tails, as it seems you are, I'd just order some OEM FX4/Raptor tails off eBay or Amazon or something. They're fairly inexpensive and look cool. As the guy above said, just swap in new bulbs if you really want to. Only one I've swapped out is the reverse light bulb because the output was pathetic. The others work perfectly fine.

 

So i crawled under and looked around. Saw a wire and loom that didnt look like it belonged there tested it and didnt get any response from my test light. Checked the rear running light fuse #40 in the truck cab and got a positive reading so i think what im going to do is unhook the led tails and check and see if a halogen will light up for running lights. But im still lost as to why i dont have license plate lights.
