i decided i wanted to replace every bulb on the car (apart from dipped and main beam) with LED stuff so it would give a clear white light rather than the sh!tty ginger stuff thats already there.
so, not knowing what bulbs were what it seemed a bit of a guessing game..
so heres a quick list of what i have found so far, not alot but i am hoping others can add to this and it can then be used for reference in future.
so :
Side lights = 501/w5w
Dipped beam = H7
Main beam = H1
Fog lights = H3
Rear number plate lights = c5w
Sunvisor interior lights = c5w
Interior light = c5w
Door puddle lights = c5w
Map reading lights = 501/w5w
Boot light bulb = c5w
Front indicator bulb = py21w/p21w
Rear indicator bulb = py21w/p21w
Brake light bulbs = p21w
Reverse bulbs = p21w
Fog light bulb (there is only one) = p21w
Tail lamp bulbs = R5w for low spec models - R10W for GTI's and all models with dark tinted rear lights.
