The CL06 from Ravemen is an innovative and easy to use rear light. It features four sets of COB LED's arranged in a cross pattern to maximise visibility through a large lit area and more diverse flashing patterns. It has a max output of 50 Lumens on warning mode and is a great light for street commuting or city riding at night. Built in sensors detect braking or vehicle headlights (>50lux) approaching from the rear. When either of these sensors are triggered they activate the eye-catching warning flashing mode at maximum 50 Lumen output to boost the riders visibility.
