This is the replacement bulb in Xenon gas for the twin headlight bulb unit stock on all Victory Vegas, Kingpin, and Hammer bikes that come with or without the HID headlight. This replaces the Hi-beam (HID bulb stays on) in the bike and gives the whiter, blue hue light, making the Hi-beam look closer to the light in the HID unit. This also is the same bulb in the new, 2007 and newer Arctic Cat Twin Spar Chassis sleds, and in the 2006 and newer GM Surburban's and Trucks. This package contains a pair (2 bulbs) per the price -$29.95.
