This adapter was so easy to install. It feels like a higher quality adapter too. It lets me use my driving lights on both high and low beam. The lights are nice and bright too. This adapter is a great value. It is a plug and play type, so there are no wires to cut or splice into.

I thought I needed something after driving at night exiting a raining and overcast and slightly foggy night. I wanted my fog lights to stay on, but when my intelibeam switched from dim to bright and back to dim, my fog lights would turn off and my dim lights just didn’t seem to be enough during those conditions so I would manually turn my fog lights back on. This process happened over and over so this harness is a good fit for that.Once I got the truck’s harness out, the plug and play module was easy to install. It snapped into place and was easy to insert back into my truck. I checked the functionality and everything worked as advertised. The build quality seems good as the wires were neatly wrapped and the connectors appeared the same as the ones in my truck.

I installed this on my 2025 Sierra and it worked exactly as described. The fog lights and low beams now stay on when I switch to high beams. The harness plugged right into the factory connectors without any cutting or splicing.Installation took about five minutes and everything fit perfectly. All the lights come on together and there are no warning messages on the dash.This is a great upgrade if you want more light output at night with almost no effort.✅ Pros: Quick install, no errors, works as advertised⚠️ Cons: Only fits specific years so double-check compatibilityGood for: GMC and Chevy owners who want all lights on with high beamsNot for: Older trucks with different wiring
