The Push is a self contained, 165 lumen vessel of visibility. With an easy push of the oversized on/off switch, you quickly toggle through high, low and flash mode. The power of the front light is augmented by independent light pipes that emit through side windows ensuring over 260?? of visibility. A simple hold of the button allows the side flash to be disabled so you can focus solely on the twists and turns ahead. The Push is mounted to your bars utilizing Princeton Tec's proven bracket system, so you can not only take it on and off instantly, but you can be sure of its firm and reliable grip. Wt: 4.1 oz.
