Looking to change my sidelight and headlight bulbs on an 03 cabriolet. Can anyone tell me what I can put in to make it look more modern i.e. whiter rather than the yellow bulbs I have? I've dfone loads of searches in the past about putting in HID kits, but I think they're illegal unless you have washers and proper levelling, so it would fail MOT? Can anyone give me the K level and H number? of the bulbs I would need please? Also, which are better, night breakers or Phillips blue xenon? Are the Philips blue xenon completely legal or a possible MOT fail?
