Sometimes you need all your light’s power on dark trails, and other times you just want to be seen – the BUSTER 400 has the right solution for any biking situation. You can choose from five different modes to adjust luminosity and battery life.
Only the modes that you need
The BUSTER 400’s five pre-set mode profiles make it very easy to use. 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 400 lights up just the way it was when you shut it off – in the same mode and with the same profile selection. The profile also always stays the same as your last selection. This makes it easy for anyone to get started quickly.
Battery indicator provides an overview
The BUSTER 400 lets you keep an eye on the battery level at all times. During the ride, the six-level LED indicator continuously displays the power left in your light. When it is shut off, a short click on the On/Off button is enough to check the battery level. While charging with the USB-C cable, you can tell from the LEDs how much progress has been made. After just three hours, the BUSTER 400 is completely charged.
Compact and lightweight
Light Guide improves your lateral visibility
The SIGMA logo on the longitudinal sides of the BUSTER 400 functions as a Light Guide. This is not only a visual highlight, but also provides significantly greater lateral visibility in traffic, enhancing safety. This lets vehicle drivers and others on the road see you better.
Osram LED for a perfect lighting pattern
In urban traffic or on fast rides on roads, the BUSTER 400 keeps you from missing anything in the dark. The high-quality, high-power Osram LED and the converging lens developed specially by SIGMA gives the BUSTER 400 very even light distribution across the entire lighting pattern.
MOUNTED IN SECONDS
The BUSTER 400 can be mounted on the handlebars in a matter of seconds thanks to the silicone bracket. It can be positioned horizontally or vertically as needed so that it can be perfectly positioned 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 400 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 400 with a double click. This function ensures that you can put the light in your pocket without any trouble and without inadvertently switching it back on. A long press on the On/Off button shuts to device off again.
Ready to go even when it is wet
The BUSTER 400 keeps going even in bad weather! It is resistant to splash water in accordance with the international IPX4 standard. This means that riding to work or taking the racing bike out for a spin is no problem, even during wind and weather.
ALSO FOR HELMETS
There is a universal helmet bracket for retrofitting the BUSTER 400. With this mount, the light will stay securely on your helmet – even on very bumpy night rides!
TIDY COCKPIT
A special adapter for the SIGMA Short and Long Butlers lets you attach the BUSTER 400 – 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.

FLASH MODES FOR MORE SAFETY
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.
CONVENIENT MEMORY MODE
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.
VISIBLE FROM ALL SIDES
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.
POWERFUL AND RESOURCE-CONSERVING
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.
THREE-LEVEL BATTERY INDICATOR
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.
SMALL, BUT … WOW!
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.
NO-TOOL MOUNTING
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 ALL-WEATHER LIGHT
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.
