hey guys, just a quick question. ive got a V plate A3 Pre-Face Lift Turbo. the N/S/F headlight has been replaced at some point in the cars life and the fog light bulb is different to the drivers side. basically whats the colour of the wires that goto the bulb as mines been changed at some point. is it grey / brown / black or something different? the n/s/f has a H1 Bulb as the fog light and the drivers side has a H7 bulb.
