As I am aware that our stock xenon bulbs are D2r. If I buy D2S bulbs (which are for projectors), do I need to modify them in order for it to work with our original housing or is it a perfect direct replacement?

 

Yes, you do need to modify them. The D2S and D2R have different notches at the base.

 

I was told from suvlights.com that they are both identical except the d2s doesn't have the covering on the buld that the d2r has and there is a little notch that you can sand off or something.

 

That's the major difference, D2R bulb is designed for reflector housing like G35s, it has a black strip which can be sand off to covert to D2S bulb.

Also the difference is the base, the D2S just can't fit into a D2R socket without cutting a notch on the other side.

I just don't understand why people want to drop D2S into the G35s, they just create too much unwanted glare on road.

 

A D2S will have about 13% greater output in terms of lumens. A philips 4100-4300 kelvin D2S puts out approx. 3200 lumens. A philips D2R puts out approx. 2800.

In terms of the glare, the people who have done it say that there is not an appreciable difference in glare.

 

It will have glare in some degree, not to the driver behind the wheel, but to the drivers in the opposite direction. Our car has refective housing, that's why Infiniti didn't use D2S in the first place. And that 13% greater output is coming outta the place where the black stripe is on the regular D2R bulb, it is there for a reason..

 

I have D2S ultinons coming for my coupe. I'll put them in, take some pics before and after against a wall under the same conditions.

I believe that there won't be an appreciable difference in glare.
