HID 35W above required headlamp washer by law. Any HID required auto levelling by law. Some car come with only 25W so do not required washer but the light output not as bright as compared to those 35 and 55W HID.

Please note that those OEM relector headlamp designed for halogen is different with those reflector designed for HID. The reflecting angle designed in reflector type HID headlamp is different from what you think. No matter you use after market D2R HID for reflector designed for halogen based headlamp, you will still make the opposite driver uncomfortable.
