Up for sale is a set of custom built headlights with RGB Bluetooth controlled halo's installed. Fits 03-06 Silverado models, and includes upper and lower headlight housings, wiring, Halo drivers, and Bluetooth module. Everything you need to install and get going. You control the lights using an app on your smartphone and can create hundreds of custom colors, strobe, flashing etc. I paid $1200 for these, asking $500 OBO PM for more details.
