I thought they were D2S, but i also find on many stores that D2S is for projection lenses.

And that D2R are for reflector, which did you buy as a replacement?

 

(cough, cough)

 

I really have no idea what you are talking about. Are you talking about light bulbs?

 

HID bulbs to be specific

 

well, what kind of xenon hid kit do you have? you would only buy a D2S/D2R bulb usually if you had an OEM ballast (like a 2002-2003 maxima HID headlight). I'm guessing you have an aftermarket ballast, which usually has these male/female pair connectors. So you would need a set of xenon bulbs rebased to a 9004-style bulb, unless your ballasts actually came from a car manufacturer?

 

They both have a D2 base but the D2R bulbs use a metallic strip that protects from unwanted glare. So the D2R bulbs are used in reflector-like applications and the D2R are used in projector-like apps. If you are looking for a brighter bulb go with the D2S but I highly recommend you do a retrofiit if you haven't already. They are really too bright for our wimpy reflector headlights.

As for your question, usually if you blow a bulb, you can use any kind of bulb that is D2#. As long as it is from the same base.
