I ordered these taillights from American Trucks(https://www.americantrucks.com/atr-led-tail-lights-black-smoked-tl-dram09-led-bk-sm.html) but didn't realize until I got them that they work with factory halogen taillights and mine were LED. I spoke to support and they suggested I get a convertor harness to get it working. This is the harness I got (https://www.amazon.com/dp/B0DWS4X4NN?ref=ppx_yo2ov_dt_b_fed_asin_title). The lights work but I noticed when the truck is off and I lock it, the little lights on the side stay on and flash really fast. I will attach a video of the lights and the lights plugged in. Is there anyway to get these working or do I need to just send everything back?
It won't let me upload the video but the lights are like half power and flash really fast. I also want to mention that the taillights and adapter both have a box(assume some kind of resistor) on them. I have tried it with only one connected at a time and also both unplugged, same thing. Any ideas here?
