Princeton Tec Switchback 2

The Switchback 2 falls between 1 and 3, but that does not mean that it is simply in the middle. With two Maxbright Rebel LEDs, the Switchback 2 can jump from helmet to handlebar and back with hardly any notice. It has the output and burn time to be a primary, or a helmet-mounted secondary. Make up your own mind how you use it. Either way, the beam, the power and the sheer jack of the Switchback 2 defies shallow definition.
