Driving through a small local city today and was pulled over by Police cruiser. After he ran my plate, he came up to my cycle and I asked what I did wrong? He was very polite and stated he needed to inspect my bike for safety because my headlight was flickering. Wondered to myself if my CCW came up on my motorcycle plate like it does on my truck plate but wasn't about to ask him. I informed him that bike has a headlight modulator and that the headlight modulator was doing what it is supposed to do for my safety and explained how they work. He said that he has been riding for 2 years and never saw a headlight modulator and stated "But I Ride a Harley". Showed him a copy of the Federal law stating that headlight modulators are legal in all 50 states and told him that you can install them on any make of bike. He asked if he could take a picture of the Federal Law copy, thanked me and sent me on my way. I have to agree with him about not seeing modulators in this area which make mine even more noticeable to the on coming traffic and that person who is about to pull out in front of you from a side street. Have only seen a couple other modulators in my travels but they were in the Youngstown area.
