  • 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. ... show more

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

  • No Brainer
I Highly recommend this all lights in mod for optimal brightness, especially on backroads like I drive! It came with a well designed motherboard that was plug and play, fit first try. Best value to get brighter lights without having to spend a few hundred dollars.

  • I can see better
Excellent product. Very easy installation. Now all four headlights come on and I can see much better. Lots of deer around here and I need all the help I could get seeing at night. Thanks for a great product.
