ALright i have an 04 g35 and the light houseing has gotten pretty messed up with the daily driving and just time. So I have purchased a set of 06 projector oem headlights.. My question is can i continue to use the same bulbs that i already have on the car. and the next question is i want to replace the fog light bulbs for yellow, does anybody know the size and code for the light bulb. if so i would appreciate the help

 

Prican, I'm not 100% sure about the '04 bulbs being used in the projector headlights. Try doing a SEARCH under (projector headlights) chances are very good you'll find someone that's made the swap....probably several!

Here is a lamp replacement guide:

Just look up the 06 G35 to see the all the bulbs. The answer to your first question though is no, you cannot use the 04 bulb in the 06 assembly. The 04 is a D2R and the 06 is a D2S, they are not interchangeable. The fog/driving bulb is an H1. I did this swap myself and it's not too bad as long as you have a friend and some beer handy.
