Well, I've had these led lights in for awhile. They are extremely bright and i am constantly getting flashed to dim my lights. At least they are noticing me and from a long way off.
Now that being said, I've taken izzy out for a few late night rips, out on some backroads with with lil to no ambient light. The amount of light cast off by these LED's is amazing compared to the stock lights. Now that being said the reflector is designed to use an incandescent bulb and not directional light like LEd. It captures the majority of the light but a lot spills out to the sides, basically it is not focused. . Now if I can only convince ducati to make a TIR lense(captures about 90% of the light and focus it straight ahead).

In all fairness i will keep these bulbs in, they provide better visual queues to cagers, they get noticed , light up the immediate area out to about 20m extremely well, the ditches/shoulder are now visible. The stock bulbs the shoulder was dark but i would get say 30m, I can still see with the led out that far, the light the beam just does ot illuminate the road. However signs in the distance are lit up well before the stock bulb was. I've switched back and forth a few times. No I did not take pictures. I was riding.
Verdict:
-Leds are a much better light
-The reflector is not designed to capture the light of an LED(they stick out further so a lot of the light is lost to the sides as it is past the edge of the reflector.
- cheap replacement will last forever, well a darn long time.
-i can live with the lack of beam lighting up the road as the vast majority if roads i ride on at night are lighted anyways. And i rarely travel on highways here at night(too many deer/elk), christ they are in the downtown areas as well.
So in a nutshell I am liking the led lights.
