Using new Chip On Board (COB) technology, the Blinder Bike Light Twinpack produces a punchy 200 lumens up front and 100 at the rear. Both lights are brilliant for attracting attention on the road or trail in all light conditions. Blinder lights are some of Knog's most individual bike lights ever, adding serious personality to you ride. Be seen from up to 450 metres away. Easy On, Easy Off - Blinder fits bars and seat posts 22 - 32mm in diameter, and head tube profiles with a circumference of up to 7.9 in using the additional large silicone strap. Charge Indicators - When your Blinder is running low on battery, a red LED will light up next to the button. This ring will turn green and then turn off once the Blinder is fully charged. Integrated USB Connector - No charging cable is required. Blinder's integrated USB-A connector plugs directly into USB ports, and charges in just 4 hours. Blindingly Bright - Blinder is a seriously bright option for any cyclist. Efficient Chip on Board (COB)...
