A xenon lighting kit for one bulb: it gives a brighter, whiter light than a standard halogen bulb. The kit usually includes the bulb and an igniter (ballast); check the exact contents with the seller.
Before installing, confirm the base type of your headlight and the voltage of the electrical system. Not every headlight optic is designed for xenon: to avoid blinding oncoming drivers, the headlight must have a suitable reflector.
