Thats the type of helpful reply i was after.
yes the car has canbus. It even tells you if a number plate light is out....
I didn't even know you could get Whiter halogen bulbs so there is my answer, thanks.
Ive also been doing a bit of digging and its also possible to fit canbus friendly LED units to the foglights that wont be too bright, but ill see if the whiter halogen bulbs are any good first.
I just dont like the yellow, compared to the nice white of the headlamps
