Have done some searching through the Forums on this topic. Have also read Auto Express review and both seem to come up with Philips Xtreme Vision as being the best. Just wondered if anyone could provide feedback that have any experience if these are in fact the ones to go for. My A3 lights have always been rubbish, but since we swapped wife's car for an A4 with Xenons it has made it even more apparent. The A3 is due to be changed in the new year for either another A3 or A4 but as it is for work it probably won't be an S Line and therefore won't have Xenons. Whatever it gets changed for will probably have standard bulbs which I will want to change.
