This time tomorrow night I may be the owner of a 5door 58 reg audi A3 s line 140, I like the look of the led day light running lights is it an easy up grade ? Or do I need to buy new head light clusters ? Also can I get nice bright head light bulbs that look like xenon with out coursing errors on the dis really looking forward to my first audi, and is there and audi members clubs ect on the south coast ?
