Recently a friend of mine's daughter, her husband, and another couple were riding, and a car pulled right out in front of them, one of the rider's spattered the side of the car and hit the windshield. another hit the side of the car and another laid it down and sustained slight injuries .. The last rider was able to stop.. two of them got messed up pretty bad. After that I decided to get a headlight modulator installed. it took about 10 minutes to install. I was against them but after using it for a couple weeks, I'm a believer in them, I was riding down the road with the headlight flashing and noticed a car on a side street, As I got close the car started to pull out then stopped.. as I passed I noticed A Young girl had a cell phone attached to the side of her head.. I firmly believe that the flashing caught her attention.. Now I'm wondering what you guy's think of the flashing head light.. This modulator works on high beams and when you flip the switch to low beam it cancels.. plus it has a built in sensor that prevents it from working at night or low light conditions..
