Thr XK Glow Laser Light Bars combine the latest in both LED and laser technology to create the ultimate in distance lighting. The outer reflectors are stacked with genuine Osram P9 LED chips surrounding the laser in the center. The Osram chips work hand in hand with the laser to create a darkness piercing spot beam. And of course, the Laser Light Bars feature a unique stacked halo DRL for when you aren't blasting through the dessert in the middle of the night!
