Lights won’t stop hyperflashing??

[farrari]

I have a 2017 Silverado 1500 High country with factory led tail lights. I bought aftermarket smoked led taillights. Lights are supposed to be plug and play and have resistors that come with and plug in but the company doesn’t make them for oem factory taillights. So I got new tail light harnesses for like an lt model and still have hyper flash. I bought plug and play load resistor harnesses for these harnesses they plug in perfectly but still hyper flash! What can I do? Can I have the bcm or ecu tuned to change the resistance as I know these new trucks don’t have flash modules

You should not need resisters.  You have factory LED already.

Checked that site and the video states the lights you have will not work with a vehicle that came with leds.

Rukus that’s what I thought but still flashes and I think it’s cause these lt model wire harnesses don’t have that pin in the plug in for the built in led resistor

Snowcamo yes I know and I contacted them and they don’t make ones made for oem leds and no other company makes these lights and I like these the most so I bought different wire harnesses and it works but have hyperflash

The only thing I can think of is the load resistors are the correct ones you need so that's why you're still getting hyper flash.

The resistor harnesses I have have two 50w 6ohms to each bulb which as far as I’ve seen or heard is the most common

Have you considered splicing in the resistors to the harness?

That’s what I started off with I bought some resistors but before I did anything I did reading to make sure I did it right and saw I needed two resistors per bulb and at the time didn’t have enough resistors and saw these plug and play harnesses with resistors built in so I figured that would be easier

Does anyone know if you have to have the exact wattage or ohms going to the bcm  that it’s tuned to or can you have more? Cause if you can have more in that case a bigger resistor should work theoretically or not??

Have you had a chance to put the factory lights back in to make sure everything on the truck is still working correctly? You might have shorted something out with the new lights.

JomCost2014 no I have not. That’s a good idea I never thought of that. But since I changed the wire harness from the led one to the regular harness with bulbs wouldn’t it still hyperflash with regular bulbs back in or not? Or are you saying the old led harnes and lights and everything??

it probably will be PITA, but I would put it all back to stock form. Maybe one side at a time just to compare what is going on, maybe easier to track down the problem that way.

What is PITA snd if it does work stock then I’m back to where I started correct? And thanks for the help!
