I personally like the red. Not to mention I got arrested 2 years ago for having blue lights on the underside of my avalanche. Theres more to that story...I called the police to report a hit and run a black benz smashed into my truck (f'ed the benz up) did minimal damage to the truck so i pulled into the gas station called the police and they come look at my truck see the light strips underneath (which are NOT ON) tell me i am under arrest...never took accident report just arrested me and impunded my truck....The charges were later dismissed by the judge who found it ridiculous...Oh and in the process of removing the lights on my truck they broke the grill and headlight which cost me nearly 1300 dollars which they never paid....anyways
I think someone could figure out how to do this if they want by looking at the pictures....

Stick with the red...the stock interior red lighting in the TT is probably the best I have ever seen in a car.

My buddy has an all blue interior vr6 and that just reminded me of his interior.

 

a lil to much color but i dont think the white looks all that bad,i still prefer the red

 

If anything, I'd like to change the white LED's of the cluster to red, I miss the all red display of my A4. Less eye fatigue too.
