Important
Never touch the bulb glass with your bare fingers. Grease and oils from your fingers vaporise from the heat and will leave a deposit on the reflector, which may damage it.
You need to make sure that the new bulb is of the correct type:
Rear brake light | H21W LL |
Turn the car off.

Insert a screwdriver behind the fog light's narrower short side and pry it out.
Unplug the connector.
Turn the bulb holder anticlockwise and pull it out.
Press the light bulb and turn it anticlockwise to remove it from the holder.
Insert the new bulb into the bulb holder and turn it clockwise.
Put the bulb holder back in place and turn it clockwise.
Plug in the connector.
Insert the hook on the wide part of the fog light unit into the rear bumper and push the unit in until the clips fasten into place.
