BUSTER 800 /

Light up the night

Smart LED bicycle lighting for more safety

With the rechargeable lighting set consisting of the BUSTER 800 and the BUSTER RL 80, you’ll never be in the dark. With 800 lumens and a range of up to 170 metres, the BUSTER 800 front light always has enough power, even in the dark forest. Thanks to five different light modes, you can individually adjust the luminous intensity and battery life and enjoy up to 30 hours of riding fun. Five preset mode profiles simplify operation. Depending on your needs, you select the appropriate profile and then switch only between the light modes that you actually need at that moment. With 80 lumens, a visibility range of 1500 metres and a runtime of up to 12 hours, the BUSTER RL 80 rear light ensures that you cannot be overlooked. The flash modes for day and night let you ride even safer on your bike.

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!


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 you cockpit neat and clean. The adapter is available as an accessory in the online shop.

Full power, long burn time, or even more safety thanks to the flash mode? The BUSTER RL 80 lets you choose among five different modes – providing the right one for every situation!


The BUSTER RL 80 is equipped with three additional flash modes that make your ride even safer, day and night. The Day Flash with its two pulsing red LEDs lasts for 4.5 hours, drawing attention to the cyclist. In Night Flashing mode, the USB rear light can continue flashing for 6.5 hours. For longer rides, the Eco Flash mode provides additional visibility in road traffic for up to 12 hours.


The memory function ensures that the BUSTER RL 80 always switches back on in the mode that it was in when it was switched off. This practical feature makes it easy for anyone to get started quickly.


The BUSTER RL 80 ensures that you are seen even from the side. The rear light has a 240-degree angle of radiation, making you even more visible. This is an important safety feature, especially in city traffic.


The BUSTER RL 80 has an integrated lithium ion battery and is recharged via the USB-C port. This not only eliminates tiresome battery changes, but also saves resources, making the light sustainable. The rear light takes no more than two hours to charge completely.


A short press on the operating button shows you how much power your BUSTER RL 80 still has. This enables you to switch to a more power-conserving lighting mode if you need to. The battery indicator has three levels. This gives you confidence at all times that you have enough power to get back home.


The BUSTER RL 80 is an especially compact and lightweight rear light (just 29 grams) that you can easily stow in your pocket. Mounted on the seat post, the slim rear light fits perfectly on any bike.


Especially practical: You need no tools to mount the BUSTER RL 80. The silicone strap makes affixing it to all common seat posts easy and fast (just seconds).


The BUSTER RL 80 is resistant to splashing water in accordance with the international IPX4 standard, so it can handle a downpour with no problem. The battery-powered rear light is a reliable companion in all kinds of weather.

Switch-on protection

You can turn on the light with a double click. This function ensures that you can stow the BUSTER RL 80 in your jersey or backpack without any trouble and without inadvertently switching it back on. A long press on the On/Off button, which can be operated easily even when you have gloves on, shuts the device off again.
