Had these in my mini d2s projector for about a month or so. Still very stock 4200k color, so not even close to burning in to 5000k. I bought them because I wasn't happy with my mini's, but adding perfume to a turd doesnt change it from being a turd. Granted, they did help a lot compared to the morimoto 5000k bulbs I had in before. I just put the morimoto's back in to sell these, and they really don't compare to the philips. I'm selling these bulbs in hopes of using the money to buy some better projectors (fxr's probably). I'm asking $50. Or shoot an offer. I will also be selling the mini d2s later too, so if interested let me know. If you have a first gen I can sell you the whole headlights already retrofitted for cheap (pics in build). Hit me up on here or txt me anytime 707-601-437seven.
