Boon to bike riders

Sometimes even compact car drivers and motorcyclists fail to trip the sensor at red lights to turn them green.

But this is especially true of bicycle riders.

So Nat Collins invented the Veloloop, a bike attachment that uses a battery to trigger the sensors.

There is also a LED light that tells the rider the sensor has been tripped.

It is in beta--and users say this shortens commutes by a significant amount.
