Product Description LUMOS Firefly Single helmet light - 3-in-1 LED with smart functions Firefly is a compact LED auxiliary light for attachment to a bike helmet. It combines three different LEDs: a red one, a white one and a yellow one. This means that it can be used as an additional rear light, as an additional front light or as a flashing light, as desired. Firefly is powered by a rechargeable battery and recharged via a USB cable. The battery life is up to 35 hours, depending on the light mode. Thanks to Bluetooth compatibility, you can even let the light communicate with your LUMOS helmet, your remote control or the LUMOS app on your smartphone. In the single version, a single Firefly is supplied with mounting material.
