Brand new One pair (2) of GTR Lighting 12V 35W Dual Beam Bi-Xenon HID replacement bulbs for 35 Watt HID Conversion Kits.

These are genuine xenon HID Bulbs that require a ballast to operate. These are NOT those cheap ones that do nothing at all. The GTR Lighting bi-xenon HID bulbs are called "swing" bulbs because they use an electromagnetic base that "swings" the bulb in and out inside the headlight. This change of position inside the housing creates the high beam and low beam function.
