HID's in Q45 Y33

What size lights you guys running in your hid's? i just got some headlights for my y33 but need to know what size bulb i should be running. i tried h7's and they too big :pat::signdammit:

what year are the headlights from? 97-98 is H4 99-01 is D2 and if you have JDM  halogen headlights the size is still H4 even though there is a separate H1 (I believe) high beam

D2R is the correct bulb for the ones that come with HIDs Stock USDM
