Recommended 7-way/4-way Adapter For 2021 GMC Sierra 1500 To Recognize Trailer W/ LED Lights
Question:
What adapter is best for LED lights on my 2021 GMC Sierra 1500 connected to my new trailer with LED lights? My current adapter has a intermittent blink when connected and my lights are off. 7 way/4 pin adapter. Do have to do something to the truck computer to fix this issue? Please advise. Thank-You!

It is pretty common for new vehicles to have issues with registering that a trailer with LED lights is connected due to the power draw being so much less than the computer on your 2021 GMC Sierra 1500 is expecting to see.
What you need is the 7-Way to 5-Way/4-Way Trailer Adapter for Vehicles with Lamp-Out Sensors Towing Trailers with LEDs # C35FR which has built in load resistors allowing your vehicle to recognize the trailer, and power the lights correctly.
