where can i get these bulbs?..

D2S 6000K Low-beam

i believe i have d2r stock.

i thin this would be a good upgrade.

what exactly is the difference between d2r and d2s.....other than the S and the R?...

 

Unless you have projectors... use d2r... d2s is the bulb used for projectors since it shoots lights all over the place, without projection ur lights will look sick, but no aim so less light to see with(if you know what i mean). If you put it in your stock housing, it's gonna cause more glare to other drivers than helping you see at night. Otherwise use d2r. I'm planning to buy Philips d2r 6000k(BMW/Audi HID). They are hella sick on my friends 2002 Honda Accord V6. Light up like 5 lanes. I don't plan to buy projectors so that's why staying d2r.
