Fog Light replacement guide
Just had to replace one of the fog lights on the drivers side as it had smahed to due to a stone hitting it I think. I got a replacement from ebay for abour £25 delivered, easy to find.
For the drivers side I removed the tow eye cover grille just by pulling it out. There are two phillips screws towards the centre of the car at the top and bottom, once these are undone you can gentley pull the light out (watch for sharp glass shards if smashed like mine!). Disconnect the wiring from the back once you have enough slack and watch where that wire goes as to not loose if back in the bumper.
You twist the back of the fog light unit to access the bulb, swap or replace as nessecary. Reconnect the back and make sure it works, then tighten it all back up and clip the grille back on.
