Hi Guys, Looking for suggestions to replace the external halogen bulbs on my A4 B8.5, i've seen good things about the Philips Diamond Vision bulbs but would like some ideas for the DRLs. also wanting to know: 1. Will I have to remove the headlight to change to bulbs? 2. Will I need to cut the headlight to change to DRL? The headlight unit I have is the same as the attached.
