Deceleration sensors are becoming more common, but here's one that is linked to the brake cable. So you could "flash" your brakes to get attention.


i ride about every other night, a hour or two, lots of people do in NYC, especially in my area, Far rockaway boardwalk, i've yet to see anyone with deceleration censors based brake lights, half of the people have flashing lights, some even changing pattern lights, some have no lights at all, so i have to rely on my own headlight to see them, actually i think most of the bikes with lights, where i ride, are rental lime E bikes.
