At first, I replaced the stock "yellow ones" with PIAA's.
That did not look right because the color did not match the HID's
Afterwards, I got some 18w Polarg M6 which was kind of better, but after a few months, the color started to fade. It got so bad that I had to pull them out.
So I'm back.. Looking for the best bulbs out there.
Anything new come out recently?
Thanks

 

How about Polarg M4? It's safer than M6 and whiter than PIAA Super Plasma.

Or you can try Xtreme Super White from PIAA. Let me know the result 'cause I don't really like my PIAA SP either.

 

Extreme superwhites from Piaa??
Thanks ARisto, sounds like a plan.
Anyone in here have those??
