Guide to Installing Xenon Headlights

Model: Audi A4 B6 - Years 2000-2004
Part: Xenon headlight kit

This guide shows how to install an aftermarket xenon headlight kit.
Provided that the installation complies with legal requirements set by traffic regulations (projector headlights, headlight washers, automatic leveling), the final effect is quite impressive, and it significantly improves visibility.
The installation involves removing the front headlights and installing the ballast (the control unit that manages this type of headlights) and the new bulb.

The car in the video is an Audi A4, but the installation is similar for many other models.
