Possibly a silly question but they are usually the ones that bite you in the ass... My car (VW CC GT) pinged up a failed headlight bulb warning this morning. I was passing the local VW dealer, so called in. £180 for the bulb and £109 to fit Amazon will deliver some Osrams for £47 each (£57 for Night Breakers) tomorrow. Just to need check the fit. PowerBlubs and ECP reckon a D3S, Autobulbs a D1S. I presume it's best to pull the headlight fuse before swapping and the usual don't touch the glass applies but anything else to watch out for? Thanks!
