These are a junk Chinese product
These are a junk Chinese product! If you want something that works, look elsewhere.... and don't be looking for the lowest price or you'll just get more Chinese garbage. My experience: Low beams are high beams. Activate the hign beam selector and high beam selection are the low beams, but one light is very noticably brighter than the other and I get oncoming drivers, and truckers, flashing their high beams at me. I messed with the clocking position of the bulbs for a few days, but the problem remained, just the light pattern somewhat changed. I contacted Sealight for resolution and they sent me a corrective decoder harness to cure this "known issue." I installed the corrective harness and the result is the driver's side light is on low and the passenger side beam is on high. Activate the bright light switch, and you guessed it, the driver's side light switches to high beam and the passenger side switches to low beam. I changed the decoder harnesses from side to side, no change. I switched lights from side to side, same issue, just different sides. Obviously the wiring in the lights is incorrect; at least one of them. While troubleshooting and working with Sealight over the course of a weeks, I did go beyond the 30-days exchange period, so I cannot return them. I had Cougar Motor Ultimate LED lights in these reflector housings before and they worked great! At least for 366 when they fell out of their 1-yr warranty and failed in a matter of weeks. After the second set of Cougar lights failed I switched to the Sealight product. I did have one known good Cougar light and placed it in each of the housings and it worked fine. I removed all of the Sealight parts and reinstalled my old halogen lights, and they worked perfect. Just too dim for both the reflector housings and my aging eyes. So I have confirmed that there is no issue with my Ford Factory wiring harnesses or my truck's ECM/ computer(s) not properly reading LED lights. And I knew that before the customer service person at Sealight suggested that my "not that old" 2006 Ford Super Duty truck, that has spent it's life in southern California where there is no weather condition that would adversely impact any wiring harness, nor do I have a rodent infestation under my hood. Bottom line: Junk product.
