Versatile equipment for every occasion The BUSTER 400 front light is a versatile companion for city riding. Whether you're commuting to work, school, or on a road bike adventure, 400 lumens and a 120-meter beam range won't leave you in the dark. Depending on the selected light mode, the light lasts up to 30 hours. Five pre-defined light profiles guarantee additional user convenience. Cyclists can simply select the profile that best suits their needs and then quickly switch to the desired light mode. Precise LED indicators located on the top allow you to see how much power is left in the battery. Key features Versatility - five lighting modes Sometimes you need full power on dark paths, other times you just need to be more visible in inclement weather – the BUSTER 400 has features for every situation. Cyclists have five different lighting modes to choose from, allowing them to individually adjust the light intensity and battery life. In High mode, the BUSTER provides up to 2 hours of 400 lumens of light, and in Mid mode, up to 4 hours of 200 lumens of light. For longer rides, Low mode provides a full 9 hours of light. Night Flashing and Day Flashing modes ensure good visibility for 30 hours. Comfort thanks to predefined lighting mode profiles Five pre-defined light profiles make the BUSTER 400 even more user-friendly: depending on your needs, you can simply select the appropriate profile and then easily switch to the light mode you need at any given moment. Cyclists can choose a profile that includes only Night Flashing and Day Flashing modes, while High and Day Flashing modes are ideal for road cycling. Faster start thanks to the memory function Thanks to the memory function, the next time you turn on the BUSTER 400, it will start up with the same settings it had when it was turned off. In the same mode and with the same light profile. A practical feature for anyone who wants to get back on the road quickly. Stay up to date with your battery status The six-level LED battery indicator always accurately displays the remaining power. When the light is off, a quick press of the On/Off button is enough to view the battery charge status. The lithium-ion battery can be charged in 3 hours using a USB-C cable. Five levels on the indicator indicate the charging progress. Other features Optimal light intensity distribution and additional visibility A high-quality, high-power LED from OSRAM and a specially developed SIGMA focusing lens ensure very uniform light distribution and excellent illumination. The SIGMA logo on the long sides of the lamp serves as a light guide. This provides significantly greater side visibility, thus increasing safety in road traffic. Tool-free assembly Thanks to the silicone mount, the BUSTER 400 can be mounted on your handlebars without tools in just seconds. Depending on your needs, the light can be mounted horizontally or vertically – even on curved handlebars. Thanks to the Quick Release, the light can be quickly removed and stowed away, saving space on your handlebars. Using the integrated guides, the BUSTER 400 can be easily removed from the mount and then reattached. The SIGMA bike mount fits handlebars with a diameter of 22-35 mm. Protection against accidental switching on The BUSTER 400 is activated by pressing the button twice. The large switch is easy to operate even with gloves on. This feature allows you to store the front light in a backpack or shirt pocket without worrying about it accidentally turning on. Water splash resistance The BUSTER 400 lamp is splash-proof (IPX4 protection category) and is therefore suitable for use in wind and bad weather. Optional helmet holder The BUSTER 400 lamp also comes with a universal helmet mount. It securely and stably mounts the lamp to your helmet.
