I've been using the ADVmonster H4 rev2 bulb in my DR650 since March. HUGE lighting improvement over the stock bulb. Only issue is the aiming. The low beam is incredibly low, and once adjusted to be usable it moves the highbeam higher than I'd like. Still, on either high or low, there is much more usable light than the stock H4. I'll have to look for my original shots with stock vs LED, both have the higher portion of the beam on the left side, not sure why. Those were done in winter, inside the garage, so they are pretty poor pics of brightness/pattern though.
Mounting the retainer in the housing.
Put the stock rubber boot back over.
Install the bulb.
Low beam, ~25 ft from door.
High beam, ~25 ft from door
Low beam, ~50 ft from door.
High beam, ~50 ft from door.
Later I installed this guy to help with deer spotting on my morning commutes.
The light is this one:

30 watt 6 LED, 6" light bar
Two are 5W, 10° spots
Four are 5W 30° "floods"
ADVmonster H4 High Beam + SuperBrightLED.com 6 inch Light Bar, ~25 ft
ADVmonster H4 High Beam + SuperBrightLED.com 6 inch Light Bar, ~50 ft
After these shots I got the light bar aimed a bit lower. I had to trim the headlight shroud a bit more so I could move the light bar up and tilt it forward.
