Automotive Lighting Circuit Board Compatible with Silverado/Sierra 2005-3500 full size GM trucks 2003-2007

It was easy to install and it did exactly what it supposed to do my light's are so much better on bright

The holes for the relays are to large and therefore it doesn’t work if the holes were smaller it would be ok. You can add some solder to them and it should work out but shouldn’t have to do that if it’s made properly.

Easy to install. But has a problem with making a solid connection to the legs of the relays that trigger all lights on. Solution I found to make it work correctly was to take the circuit with the relays, turn it over with the relays in, and solder the legs of the relays to the board only on the 3 legs that need to make the connection. Once I did that and reinstalled it the all lights on mod works perfectly. Hope this information helps anyone else having the same intermittent connection issue.

No instructions had to use picture from purchase page.

It seems to be a decent quality copy of the fleece product. If you don't have fog lights it will enable high and low beam at the same time which make a noticeable difference. It came with no instructions a piece of paper with a url or qr code would have been nice but basically you remove your high low and fog relays sit this board on the fuse box over the holes for those relays and then reinstall the relays through this board.

This item does not work I’ll put it in my truck the way it told me and it did not change none of my lights from the factory settings. This is a waste of money and a rip off.

Figured for the price it’s cool. Got it and found out the relay connections on it suck. As you can see in my video, in order for it to work I had to move my relay. They need to improve on their design. The principal is solid, but they didn’t properly construct it.

Great way to upgrade lightning. Really helps light up the road.
