The Xenon HID kit includes bulbs that differ from conventional ones. Instead of a filament resistance, a special gas mixture is used, which is ignited using electric current to produce light. Xenon gas is the main component of this mixture.

A xenon kit or a xenon replacement bulb is commonly used in the following:

• Crossing lights (medium)
• Driving lights (high beam)
• Fog lights

The H7 type indicates how the kit's bulb is mounted in the vehicle socket, as well as the electrical power requirements. It is important to consult your vehicle's manual for the correct kit selection.
