Your light in the dark

Bright light on dark trails! The BUSTER 800 means that nothing is keeping you from nocturnal adventures. Its 800 lumens provide 170 metres (557 feet) of range – sufficient power even on dark forest trails. Five different light modes ensure flexibility with respect to luminosity and battery life. Thanks to the LED indicators on the top, you always have an eye on the current settings and remaining battery life. Five pre-set mode profiles provide greater ease of use. The environmentally friendly lithium ion battery keeps you on the trail for up to 30 hours, depending on light mode.

Versatile thanks to five light modes


Lumens ≤ 800
Burn time ≤ 2 h


Lumens ≤ 400
Burn time ≤ 3 h


Lumens ≤ 150
Burn time ≤ 9 h


Lumens ≤ 600/200
Burn time ≤ 5 h


Lumens ≤ 200
Burn time ≤ 30 h

Sometimes you need all your light’s power on dark trails, and other times you just want to be seen – the BUSTER 800 has the right solution for any biking situation.
You can choose from five different modes to adjust luminosity and battery life.

An eye on light modes at all times

From High Mode to Day Flashing Mode, the BUSTER 800 offers lots of options for rides in darkness. The mode display ensures maximum ease of use. You can always see which of the five modes and which luminosity you are using at the moment.


Only the modes that you need

The five pre-set mode profiles make the BUSTER 800 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 800 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

The LEDs on the six-level battery charge indicator continuously show you how much power is left during your ride. When it is shut off, a short click on the On/Off button is enough to check the battery level. The USB-C cable can charge the environmentally friendly lithium ion battery within four hours. The battery charge-level indicator helps: The five levels show how far the charging process has progressed.


More visible thanks to Light Guide

The SIGMA logo on the longitudinal sides of the BUSTER 800 functions as a Light Guide. This is not only a visual highlight, but also provides significantly greater lateral visibility in traffic, enhancing safety.

Ideal light distribution

The high-quality, high-power CREE LED and the converging lens developed specially by SIGMA gives the BUSTER 800 very even light distribution across the entire lighting pattern.


The BUSTER 800 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 800 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 800 with a double click. This function ensures that you can put the power light in your jersey or backpack without any trouble and without inadvertently switching it back on. A long press on the On/Off button shuts to device off again.

For all-weather tours

The BUSTER 800 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.


There is a universal helmet bracket for retrofitting the BUSTER 800. With this mount, the light will stay securely on 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 800 – 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.
