So the light comes on when you have ABS and yes, it's a cutout behind the gauge so you can sort of see it when it's not lit. It remains lit until you move x amount of feet. I've forgotten how far but about 10 I think. There is a wire attached to the brake line, a reluctor ring, big ass ABS pumps under the side cover, a frickin DVD that comes with the bike to 'teach' you how to use ABS and I'm sure something else. The light does not come on when you don't have an ABS equipped bike. People will sue for anything just like rolling the dice... he might win or they might settle. It's why every other sentence in the HD manual says "failure to do so may cause serious injury or death" I'm sorry for his loss, but dammit, quit making it our problem.
