I really want to get HIDs for my DA, but i have the JDM One-piece lights. What's the type of bulb or code or something for HIDs for the JDM One-piece lights?

 

JDM 1-piece lights use H4H bulbs, which is a bulb size not commercially available in the USA. There are a few PnP kits made for H4H out there, but output and beam pattern will be horrible with the prismatic lenses.

I highly recommend against an HID kit in JDM 1-piece headlights.

Best bet would be a projector retrofit with a circular area polished out clear in front of the projector.

 

Alright then, thanks. I'll probably go with the projector retrofit.
