Elevato, the warm up time is the bulbs because of the salt/gas mixture, not the ballasts. Audi uses Osram bulbs, which at ~$150/ea aren't economical for most retrofitters. As soon as my Morimotos die, I'm getting Osrams.

 

Looks great! Any pics of the whole thing yet, with the corners?

Where did and what kind of corners did you get? I want to get clear ones as well. Can you get them without the amber strip?
