<strong>2.</strong> High-intensity discharge (HID) lights are the "be all end all" of off-road lighting. These lights work with a pair of electrodes inside a bulb filled with a mixture of xenon gas, mercury, and metal halides. In addition a ballast sends a precise high-voltage charge through the electrodes to make an extremely bright light. HID lights often have a short warm-up time but then burn very bright and as such are the choice for most desert racers. These new PIAA Cross Country HID Lamps have a small internal ballast, making them easy to install on motorcycles and UTVs or to tuck in tight on rollcages or bumpers to protect them from trail abuse.
