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.


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

The BUSTER RL 150 allows you to react flexibly to the various requirements of weather and lighting conditions. High and Low mode and three flashing modes are available to you. Full power on a night ride or economical operation on long tours – no problem for the powerful SIGMA rear light.


The integrated acceleration sensor ensures that the BUSTER RL 150 knows right away when you brake. The two LEDs light up especially bright for about three seconds. This cool feature ensures more safety – not only at night, but also during daytime rides in road traffic or during a group tour.


The BUSTER RL 150 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 6 hours, drawing attention to the cyclist. In Night Flashing mode, the USB rear light can continue flashing for up to seven hours. For longer rides, the Eco Flash mode provides additional visibility in road traffic for 20 hours.


The memory function ensures that the BUSTER RL 150 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 150 is equipped with side apertures that ensure that the light can be seen at an angle of 280 degrees. This is lateral visibility an important safety feature, especially in city traffic.


Never change batteries again with the BUSTER RL 150 – the long-lasting, powerful lithium ion battery keeps your cycling sustainable. The USB-C port can be used to charge the light completely within three hours.


A short press on the operating button shows you how much power your BUSTER RL 150 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.


It is not even five centimetres long and weighs only 38 grams, so it fits discreetly on any seat post. After a ride, it can be stowed easily in a trouser pocket.


Especially practical: You need no tools to mount the BUSTER RL 150. The silicone strap makes affixing it to all common seat posts easy and fast (just seconds).


The BUSTER RL 150 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.


You can turn on the light with a double click. This function ensures that you can stow the BUSTER RL 150 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.
