Good idea, although all the lasers, L.E.D.S. and air horns in the world don't make up for looking RIGHT AND LEFT before pulling across that sidewalk and into traffic.

I've dented more than one fender in my life.

My feeling is, all the whistles and bells will do nothing because those riders that get hit are by the drivers that have no clue when they are driving about what is around them...
