Hello, in this guide, you will learn how to replace the headlight bulb on your car quickly and easily. Once you open the bonnet, position yourself at the headlamp that needs changing.

Reach behind the headlamp where the wires are located and disconnect the rubber seal covering it. Next, there is a clip that secures the bulb; unclip the electrical connector and remove the old bulb. Replace it with the new bulb, ensuring it fits snugly into the housing.

Finally, reconnect the bulb's electrical connector and reattach the rubber seal. To replace the bulb on the driver's side, you need to remove the fuse cover located next to the brake fluid reservoir.

Then, detach the cover in front of the fuse box. The procedure for replacing the driver's side bulb is the same as for the passenger side. Once finished, replace the covers in their respective positions.
