Tdub is all LED/HID, even the gauge and indicator lights. I bought the LEDs from superbrightleds.com and the HID off ebay.
I tried the 90* 1156 and 1157 replacements in the turns, but vibration killed the 1156s in just a few miles. I switched to the flat 36LED panels and glued them into the housings with a bit of silicon glue. The 1157s are still good. I have the 5W Luxeon in the tail light. Get the brightest bulb you can for the brake/tail. The Luxeon is brighter than stock. The multi-LEd indicator bulbs are too bright. Use the cheaper single LED versions.
The only change I made other than bulbs is a flasher for LEDs. Just carry the old one into any auto parts store and ask for an electronic replacement that is not load sensitive.
The HID is half a bi-xenon kit, for a car or truck, the other half of the kit is on my CB550.
