I just installed mine yesterday and I was amazed at difference in light intensity and the different modulating pattern choices you can select from to set the light too when the brakes are applied.
My wife pulled into the driveway when it was dark and I had the garage door open, as soon as I saw her I hit the brake on the bar to activate the light and when she walked into the garage her first words were, "I thought a cops bike was in the garage" her next words were "I hope you don't aggravate someone with it, but I think I like it, safety first".....
If you have ever been loved tapped from behind by a car as I have, and they say it was because they never saw you, you will try to stand out a we bit better and this light does that.
