How do you change the rear indicator on citroen c3?

First identify the failed bulb. Open the boot and unclip the nut cover on the exterior fixing. Undo the two nuts ( one outer and one inner). In the side storage compartment, unclip the lamp holder and disconnect the connector(wire) to the failed bulb. Replace the bulb and refit the unit.

Bulb sequence:

Top most bulb : Stop lights P21 W/5 W

Next is the Direction indicator: PY 21 W

Next is the reversing lights: P21 W

Next is the Fog lights : P21 W
