Flashing rear light with brake light function With the BUSTER RL 150 rear bike light, no one will miss you! SIGMA's brightest rear light ensures maximum safety – 150 lumens and a visibility of 2,000 meters make cyclists perfectly visible both on the road and in the dark forest. The practical brake light function signals every braking action and provides additional safety in road traffic. Five lighting modes allow the BUSTER RL 150 to illuminate for up to 20 hours in flashing mode. Tool-free installation, durability, compactness, and low weight make it the ideal rear light for even the most demanding users! Key features Versatility - five lighting modes Cyclists can choose from five different lighting modes, allowing them to individually adjust the light intensity and thus the battery life. In High mode, the BUSTER RL 150 illuminates for up to 4 hours at 40 lumens, and in Low mode, for up to 20 hours at 5 lumens. Day Flash mode, with two pulsating red LEDs with 150 lumens, draws attention to the cyclist for over 6 hours. In Night Flashing mode, the USB rear light illuminates for up to 7 hours at 25 lumens. For longer rides, Eco Flash mode provides additional visibility and safety in traffic, with up to 20 hours of illumination. Greater safety with a brake light Thanks to its integrated acceleration sensor, the BUSTER RL 150 light immediately recognizes braking. Two LEDs then shine particularly brightly for approximately 3 seconds. A practical feature that increases safety – not only at night, but also during the day – in road traffic or during group rides. Faster start thanks to the memory function Thanks to the Memory function, the BUSTER RL 150's light turns on in the same mode it was in when it was turned off. This is a practical feature for anyone who wants to be ready to ride at any time. Very good visibility The BUSTER RL 150 light ensures cyclists are clearly visible from the side. It features side windows that give the rear light a 280-degree visibility area. This safety feature is especially important in city traffic. Other features Three-stage battery indicator A quick press of the operating button and the BUSTER RL 150's three-stage battery charge indicator will show you how much power is left. This allows cyclists to switch to a more economical lighting mode when needed, ensuring they have enough power for the last meter of their route. Double-click protection against accidental activation The BUSTER RL 150 is activated by pressing the button twice. The large switch is easy to operate even with gloves on. This feature allows you to stow the rear light in a backpack or shirt pocket without worrying about it accidentally turning on. Energy saving and great power The BUSTER RL 150 is equipped with an integrated lithium-ion battery that charges via USB-C. The rear light is fully charged in up to three hours. This eliminates the hassle of replacing batteries, saves resources, and is environmentally friendly. Tool-free assembly Thanks to the silicone strap, the BUSTER RL 150 can be attached to seat posts up to 35 mm in diameter in seconds without the need for tools. Water splash resistance The BUSTER RL 150 lamp is splash-proof (IPX4 protection category) and is therefore suitable for use in wind and bad weather.
