This bike light set features a Sigma Lightster front light and a Sigma Cuberider II rear light. Both lights have a click-switch for ease of use and they are also waterproof, so you can ride from A to B with confidence. With up to 20 hours burning time for the front and an exceptional 60 hours for the rear, this set is a great upgrade for everyday commuting. Lightster Front Light This high-quality front light uses the latest LED technology to reach 20 LUX. It uses its wide and glare-free light image to deliver homogeneous illumination for up to 20 hours. Sigma has also equipped it with anti-slip pads on its handlebar bracket, which means that you can benefit from perfect grip even on oversize bars. Thanks to its clever slide function, the Lightster can be removed from your bike for protection against theft. Cuberider II Rear Light This rear light is great for commuting to and from work as well as exploring in low light conditions. With four LEDs and 220 degrees of visibility, it ensures that you remain visible to other road users for up to 100m/0.5 miles. Sigma has also equipped it with an easy on/off switch that can be pressed even when wearing gloves. In addition, its impact-resistant and water-resistant housing is intended for all uses. One final highlight is its tool-free mounting system, which features an adjustable rubber clamp that’s designed to fit all seatposts and rear seat stays.
