Pasenger side bulb has been starting to flicker on me i know it is the D2S and oem output is 4300k just looking for best vendor or source, to purchase from was debating slightly higher 5000k maybe nothing purple or ricer looking any input

 

When I had my IS I switched to the 5k ones which in my opinion give the best look without sacrifice light output like when you go 6k and up. I got mine off eBay. You can find name brand bulbs on there for pretty good prices. I can't say on any vendors on here just cause I have been in the market for any bulbs since getting the evo.
