Hey guys, I'm looking to upgrade to the Philips 6000k pure white hid bulbs and confuse as to which bulb size to use. I have a 2007 GT3 and according to the manual, we use D2S. But doing a quick search on google, the 2007-2008 GT3 uses "D1S" and 2010 gt3 uses "D2S".....

Can anyone confirm which is the correct bulb? Thanks

link from Sylvania stating "D2S" for 2007.. http://www.sylvania.com/ConsumerProd...RG-Results.htm

Correct oem bulb for low beam with Bi-Xenon headlight in a '07 GT3 is a Philips D2S 35W bulb.

My advice is that you stay with the oem color temp bulbs as if you go for the 6K xenons, what you 'll gain in whiteness you will lose in lumens..

if you replace one you may have a color difference because they change with age. If you buy cheaper aftermarket brands just replace the pair
