Update: After thinking a car may have flashed me the other night, I did an evening test run by riding behind my wife's car, then coming from the opposite direction. She said the MondoMotos were so bright she had to look away, and that it looked like I had my high beams on (but obviously not the main headlamp bright). These things are pretty amazing, and have exceeded my expectations. If a reasonably priced option was available to dim the lights by 25-50% (either by button or knob), I'd buy it.
Note: My lights are attached at by the front wheel fender bolts, and are angled slightly downward. I may be angling them a little more.
