Light your trail with power


Ultimate power for more safety

It lights the way even on the darkest trail: The BUSTER 1100’s innovative double lens ensures that you always have plenty of light. The two LEDs generate a powerful lighting pattern with 1100 lumens and 165 metres of beam range. If your on a long ride, you can charge the BUSTER 1100 during operation with the USB-C quick-charge function. And the six light modes can also be used to reduce brightness so that the environmentally friendly lithium ion battery lasts up to 50 hours. The memory function ensures that the BUSTER 1100 is in your favorite mode when you switch it on again.

Innovative double lens with Osram LED

The BUSTER 1100 lighting pattern is a real eye-catcher. It lights the trail perfectly so that curves and hanging branches are much easier to make out. This is possible thanks to a new double lens with two different optics and the two high-quality Osram LEDs. They ensure plenty of brightness and ideal light distribution. More fun and more safety on night rides!

Sometimes you need all your light’s power on dark trails, and other times you just want to be seen – the BUSTER 1100 has the right solution for any biking situation. You can choose from six different modes to adjust luminosity and battery life.

Mode display at a glance

From very bright to energy-conserving: The six different modes ensure you have enough light for any of your rides. The mode display on the top of the BUSTER 1100 shows you at a glance what light mode you are using.


Versatile and convenient

The five pre-set mode profiles make the BUSTER 1100 even more convenient: You can select the profile that is just right for your requirements and then simply switch between modes to the one you need at the moment. For instance, there is a commuter profile displays only Night Flashing and Day Flashing modes; racing and training rides will benefit from High Mode and Day Flashing Mode.

The light with a memory

The memory function ensures that the BUSTER 1100 lights up just the way it was when you shut it off – in the same mode and with the same profile selection. This makes it easy for anyone to get started quickly.

Battery indicator provides an overview

To make sure that you aren’t suddenly in the dark, the BUSTER 1100 shows you the precise amount of battery power remaining at all times during your ride. When it is shut off, a short click on the On/Off button is enough to check the battery level. The battery charge level indicator helps with charging: The five levels show how far the charging process has progressed.


Quickly back on the trail

If the battery does go flat, the quick-charge function will get you moving again. The BUSTER 1100 can be charged completely via the USB-C port within 3 hours. If you don’t want to wait, you can charge the light during operation with a power bank.

Also visible from the side

The SIGMA logo on the longitudinal sides of the BUSTER 1100 functions as a Light Guide. This is not only a visual highlight, but also provides significantly greater lateral visibility in traffic, enhancing safety.


The BUSTER 1100 is attached to the handlebars with a screw clip and the 3D rubber pads. It can be oriented three dimensionally as needed, so that it can be positioned perfectly for curved handlebars. The power light has a quick release so that it can be stowed quickly and compactly. The integrated slider allows the BUSTER 1100 to be pushed on and removed conveniently. The SIGMA bike bracket fits on handlebars of 22-35 mm diameter.

Double-click for light

You can turn on the BUSTER 1100 with a double click. This function ensures that, when you take a break, you can put the light in your jersey without any trouble and without inadvertently switching it back on. A long press on the On/Off button shuts to device off again.

Illumination even in the rain

The BUSTER 1100 light can penetrate even heavy rain to light your way. It is resistant to splash water in accordance with the international IPX4 standard. This means that night rides or road tours in wind and weather are no problem.


A universal helmet bracket is available as an accessory for the BUSTER 1100. This mount secures the light firmly to your helmet – even on very bumpy night rides!!

Video tip


A special adapter for the SIGMA Short and Long Butlers lets you attach the BUSTER 1100 – or an action camera – right under the bike computer. This keeps your cockpit neat and clean. The adapter is available as an accessory in the online shop.
