PThe PWR Lighthead 1100L is part of Knog’s PWR Range. Compatible with the small, medium and large PWR Banks you can build the bike light that you want. The PWR Lighthead 1100L outputs an elliptical style beam with a horizontal and vertical spread for broader and brighter road coverage, combined with an additional ring of “be seen” LEDs. You can also program the light to suit your needs with Knog’s Modemaker app – control brightness, adjust runtimes and add new light modes.
