A powerful lighting set for every occasion

The lighting set, consisting of the BUSTER 400 front light and the BLAZE FLASH rear light, is a versatile companion for city riding. Whether you're commuting to work, school, or 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 front light has a runtime of up to 30 hours. Five pre-defined light profiles guarantee additional operating convenience. Cyclists can simply select the profile that best suits their needs and then quickly switch to the desired light mode. Precise LED indicators on the top allow you to see how much power is left in the battery. The BLAZE FLASH rear light impresses not only with its brake light function but also with two flashing modes that make the cyclist even more visible. An integrated brightness sensor automatically turns on the bike light in low-light conditions. The rear light is visible from 500 m and lasts for up to 50 hours.

Key features

BUSTER 400

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.

Optimal light intensity distribution and additional visibility

A high-quality, high-power LED from OSRAM and a specially developed focusing lens from SIGMA ensure very even light distribution and excellent road 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.

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.

Optional helmet holder

The BUSTER 400 lamp also comes with a universal helmet mount. It securely and stably mounts the lamp to your helmet.

BLAZE FLASH

Brake light day and night

The BLAZE FLASH rear light features a brake signal function. Thanks to an integrated acceleration sensor, three bright LEDs alert other road users to braking for approximately three seconds. The brake light can also be used during the day without using the permanent lighting.

Four lighting modes with a light intensity sensor

The BLAZE FLASH's four lighting modes allow you to control the light's brightness and battery life. In addition to the static, continuous light, the light is automatically activated by a brightness sensor that responds to ambient light. This feature is ideal for driving in tunnels or on dark forest roads, for example. Another highlight are the two flashing modes: Pulse Flash with three pulsating red LEDs and Eco Flash with one flashing red LED. In all lighting modes, the acceleration sensor activates the brake light for approximately 3 seconds.

Good visibility and long burn time

The BLAZE FLASH headlight boasts a 500-meter visibility and a long burn time of 50 hours in Eco Flash mode. This ensures good visibility and safety in road traffic.

High-quality design

Whether your bike is more sporty or urban, the BLAZE FLASH rear light, weighing just 22g, discreetly integrates into the seat post. Its sleek, vertical shape ensures optimal side visibility.

Other features

Tool-free assembly

Thanks to the silicone mount, the BUSTER 400 can be mounted on your handlebars without tools in just a few 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 stored away, saving space on your handlebars. Using the integrated guides, the BUSTER 400 can be easily removed and reattached. The SIGMA bike mount fits handlebars with a diameter of 22-35 mm. Thanks to the included silicone strap, the BLAZE FLASH can be quickly and tool-free attached to all popular seatposts, making it suitable for use on a variety of bikes.

Water splash resistance

The BUSTER 400 and BLAZE FLASH lights are splash-proof (IPX4 protection category), making them suitable for use in wind and bad weather.

Multiple charging

The BUSTER 400 and BLAZE FLASH lights are equipped with an integrated lithium-ion battery that can be charged in three hours using the included cable. This saves money and protects the environment.
