Many vehicles have been using LED assemblies in place of traditional headlights and bulbs for years. The turn signal bulb and brake lights have been upgraded to be brighter while producing less heat. Major advancements have been made in headlights too. Instead of the old halogen bulb, vehicles are using Xenon HID systems. Many of the new headlights and bulbs require special tools and high voltage handling training to be serviced safely. Kniesel's can handle any and all bulb related services!
