I've replaced my standard bulb with a GTR Ultra Series 2.0 H4/9003. In order to do so I had to move most of the wiring bundles out of the headlight and behind the triple tree beauty cover. First I worked out how all the plug bundles would layout under the beauty cover. Then I used heatshrink sizes 1.25, 3/4 and 3/16 to cover the plugs. What was left in the bucket was the H4 connector, the LED bulb driver and wire, and the little incandescent wiring and bulb. I'll try to post pics later, my phone is being swapped.
