The German road traffic regulation-approved (StVZO) CUBE RFR Light Set TOUR USB CMPT with LED technology contains an RFR Front Light TOUR USB CMPT and an RFR Rear Light USB CMPT. A 30 lux front light illuminates the way ahead, while at the rear the tail light has a brake sensor function for added safety. The IPX4 housings are splashproof, while a battery indicator lets you know when you're running out of power so you're never plunged into darkness. Integrated batteries mean the lights are easy to recharge using the included Micro-USB charging cable. The lights mount to your handlebars and seatpost, no tools needed, and the angle is adjustable, too.
