I was riding on M-89 at 56 mph, I Sheriff did a u-turn and pulled me over. He told me I could not have a head light modulator in Michigan. Since I've had this for about 5 years and passed many a Officer I was a bit surprised.
Before I purchased it long ago, I checked and Kisan stated the fed said you can have one.
Did I argue, I don't look good in orange jump suits, so I just turn off the bright switch.
Michigan Motor Vehicle code:
(3) A motorcycle or moped head lamp may be wired or equipped to allow either its upper beam or its lower beam, but not both, to modulate from a higher intensity to a lower intensity. A head lamp modulator installed on a motorcycle or moped with 2 head lamps shall be wired in a manner to prevent the head lamps from modulating at different rates or not in synchronization with each other. A head lamp modulator installed on a motorcycle or moped shall meet the standards prescribed in 49 CFR 571.108.
