I went with 55 watt 6000ks both high and low from DDM Tuning. If I had to do it again I would go with 5000ks because they would be pure white. For the first hour or two of operation my 6000ks were very blue but a lot of that has faded and its mostly a white light with a little blue around the edges. I made my own relay harness for them as well.

 

I wonder if it's possible to just purchase the pair of 5k bulbs?

 

They do, well I know I can get them.
