If you have a GMT800, get this.
I bought 2 of these, one for a 2004 Yukon and one for a 2005 Silverado 2500HD. Installation takes 2 minutes, it uses all of the wires unlike the free method which puts all of the amp draw on a single set of wires, which is a fire hazard. They worked as advertised and are fantastic. Half of my driving is at night so any improvement in visibility is definitely welcomed. This product is awesome and I'd recommend it to anybody with a GMT800.

Fits perfectly and works well!
I installed this board in 30 seconds and greatly increased my nighttime driving visibility. Combined with LED lighting, it’s amazing!

Great value for the money. Safer and looks great! Ingeinous solution.
Works great. I've got multiple installed in my 03-06 Sierras. So much better than finicking with stupid failure prone bulbs.

Should have been standard GM
I’ve purchased 4 of these over the last year or 2. One for each of my 3 2003-07 trucks. Takes 2 minutes to install, and I even bought one for a friend as a gift for his duramax. I can see the ditches with my high beams on now! This should have been standard on these trucks. Cannot recommend enough. Way easier to install than the strange wiring bundle ones for the 99-02 to do the same thing.

Easy install and works great!
I took me less than 5 minutes to open the hood, open the fuse box, install this bad boy and close up everything. Plus it works great, just as advertised!
