The Mégane II Owners' Club

After you've got your arm in the wheel arch port and removed the plastic cover...
Remove the power connection to the bulb, on the top right of the bulb, push the top of spring upwards and then slightly to the right, it will fall down, remove bulb, replace bulb, fold spring back up and push so that it locks again and, finally, replace connector!

FYI: There are TWO types of bulb fitting.If you have no spring then the bulbs need to be rotated 1/4 turn anti clockwise to release...

1: Remove the wheel in the arch where the lightbulb is
2: Open the bonnet and unscrew the black plastic cover from above the light mount
3: Remove the little cap in the wheel arch to gain access to the light
4: Unscrew the protection cap from the back of the mounting
5: Before removing any lightbulbs, wiggle the back of the one you think is the problem and confirm by looking at the front as to which is moving
6: CAREFULLY remove the metal clip from around the bulb by squeezing it either side of the bulb
7: Carefully remove the wiring from the back of the bulb
8: Take out the old bulb and insert a new one. It doesnt screw, it just sits - safely! Ensure it is square inside the bracket though
9: Replace the clip around the bulb
10: Add the wiring to the back of the bulb and test.
