How to replace a Xenon bulb

Model: (Various brands) Various
Part: Light bulb

Let's see how to change a Xenon bulb: the YouTuber works on a disassembled headlamp from a Mercedes, but what matters is the basic procedure. Follow the instructions written on the control unit: rotate the body of the control unit to the left as indicated by the arrows, which will almost automatically eject it. Underneath, you will find the bulb; press the pins and disconnect the lamp. Always without touching the glass bulb, refit it by reconnecting the clips. Now you can reinsert the control unit, trying to avoid the wires, and turn it to the right. You should hear a "clack" confirming it is in place, and you can then refit the cover. Job done.
