Does anyone know of any decently nice, but cheaper replacement headlight bulbs that a 2003 g35 coupe can use? Maybe off of Amazon or Ebay? Haven't been able to find any

 

You can find the bulb size you need in syllabi as book or their website, or printed on the front of your headlight.

As for an OEM replacement, reflectors could just use a nice 6000K silver star ultras.

 

Found a pair of 6000k diamond white D2C HID bulbs on Amazon. Would they work?

 

On your headlights in the lower section you will see the exact bulb your car needs for the main bulb. Mine is a D2R I believe. 6K will be white with a hint of blue, gorgeous in my eyes.

Unless you have HID's on your coupe you need to stick to halogen lenses.

 

all coupes came with hid standard....I believe. the sedans didn't. ebay is the spot I get all my bulbs

 

Correct. 2003 sedans could have either.

2003 coupe should be a D2R.

I've gotten mine from DDM, however, a cheap HID bulb is a cheap HID bulb and didn't last as long as the OEMs.

However, i could buy 5 or 6 sets for the price of one OEM set of bulbs.
