55w kits wash color out and are very unecessary. If you can't see with a 35w kit you're totally blind. If you favor color over light output then look to get harassed depending on your local cops. 8000k will get you pulled over eventually I'd almost bet money on it.

A very good alternative to the junk ebay offers for our cars!!!
