Only the modes you need

Thanks to its five preset mode profiles, the BUSTER 400 offers you plenty of ease of use. Depending on your requirements, you select the appropriate profile and then only switch between the light modes that you really need at that moment. For commuters, for example, there is a profile that only displays the Night Flashing and Day Flashing modes, while the High mode and Day Flashing mode are available for road cycling.

The light with memory

Thanks to the memory function, the BUSTER 400 lights up the same way the next time you switch it on as it did when you switched it off. The mode profile also remains the same as the last time it was selected. A practical feature for anyone who wants to be ready to go quickly.

Keep an eye on the battery level

With the BUSTER 400, you always know how much battery life you have left. While riding, the six-stage LED indicator constantly shows how much power your light has left. When switched off, a quick click on the on/off button is enough to display the remaining capacity. When charging via USB-C cable, you can see from the LEDs how far the process has progressed. The BUSTER 400 is fully charged after just 3 hours.

More visible thanks to Light Guide

The SIGMA logo on the long sides of the BUSTER 400 acts as a light guide. This is not only a visual highlight, but also ensures significantly higher lateral visibility. This means that drivers and other road users can see you better.

Osram LED for a perfect light pattern

Whether in city traffic or when driving fast on the road: with the BUSTER 400, you won't miss a thing in the dark. Thanks to the high-quality LED from Osram and the converging lens specially developed by SIGMA, you get very even light distribution across the entire field of vision.

Light with a double click

You can switch on the BUSTER 400 with a double-click. This function ensures that you can easily stow the light in your bag without it accidentally switching itself on. A long press on the On/Off button switches the device off again.

Ready, even when it gets wet

The BUSTER 400 doesn't falter even in bad weather! It is protected against splash water in accordance with the international IPX4 standard. So you can go to work or out on your racing bike without any problems, even in wind and weather.
