My passenger side rear light has gone and not sure which bulb I need to replace. Its the light when you switch on your normal headlights the back automatically stay on. Is that called a sidelight or tailight?
the front fogs don't just 'come out of place' have you hit something ?
they mount from behind but I can't tell you how as both daughters & her partners Clio's don't have front fogs.
You will have to remove the front inner wheel splash guard & take a look, they may just clip in but I suspect they are bolted in
& some plastic part has either got broken or someone else has been there & left a screw / bolt out ?
Tail light bulbs are easy, the drivers hand book will tell you how to remove the lights unit and fit a new bulb.
(they push and twist just like a house bulb.)
Tip - test its working before you re fit the light unit.
