it is the left hand side main headlight bulb

open the bonnet and there should be a flap to get you into the headlight or u can just pull the bulb out, perhaps some clips holding it in.. have a look.they're not hard to change

You have to be double jointed, but the bulb is behind a cover & held in place with a sprung wire.

1 - identify which bulb it is (if u have a separate side light in the headlight casing)

2 - flip or twist the cover of the back of the headlight enclosure (from inside the engine compartment)

3 - pull the wires off the back of the bulb

4 - feel for the retaining clip holding the bulb in place, give it a squeeze & pull it back. (it wont fall off - its connected to the headlight enclosure - or should be!)

5 - take out bulb

6 - put the new bulb in, it will only go in one way, so twist the bulb a bit & u will find it sits in a couple of slots (this is to make sure ur headlight beams r aligned properly & u do not blind other drivers)

7 - Put it all back together!
