SIGMA Buster 900 Link HL Helmet Light

High-Performance Helmet Light with Link Connectivity

The BUSTER 900 LINK HL combines powerful light output with smart, user-friendly operation. With up to 900 lumens, a beam distance of 180 meters, and a wide, uniform beam pattern, it ensures excellent visibility on dark paths and trails. Mounted on your helmet, the light follows your every head movement—and is exactly where you need it. This allows you to illuminate curves, obstacles, and junctions precisely, keeping the path clearly in view at all times. Thanks to LINK connectivity, SIGMA RIDE app connectivity, and compatibility with the optional REMOTE ONE, the helmet light can be flexibly networked, configured, and controlled.

MODE DISPLAY AT A GLANCE

The 5-level status indicator lets you see at a glance which lighting mode is active. The BUSTER offers three constant-on modes—HIGH, MID, and LOW—for different lighting conditions. NIGHT FLASH and DAY FLASH add two flashing modes.

INTELLIGENT LINK FUNCTION

With the LINK feature, you can wirelessly connect the BUSTER 900 LINK HL to compatible SIGMA LINK taillights. This turns the front and rear lights into a networked system that can be conveniently controlled together.

Connect your BUSTER 900 LINK to a compatible LINK taillight such as the BLAZE LINK, HIRO LINK, or NYTE LINK. The taillight’s brake light function remains active regardless of the front light’s selected lighting mode.

A RECO LINK radar taillight can also be paired with the BUSTER 900 LINK. Approaching vehicles are displayed on a radar-compatible bicycle computer or in the SIGMA RIDE app.

MEMORY MODE

The BUSTER 900 LINK HL remembers the last lighting mode used. The next time you turn it on, your selected setting will be active again right away.

APP CONNECTIVITY

With the SIGMA RIDE app, you can also keep an eye on your BUSTER 900 LINK HL right on your smartphone. You can set the lighting mode, check the battery level, assign a custom device name, and install firmware updates.

EASY TO USE

Five preset mode profiles make it easy to select your desired lighting modes. The double-click activation lock prevents the BUSTER 900 LINK HL from turning on accidentally.

SIDE VISIBILITY

The integrated LIGHT GUIDE makes the BUSTER 900 LINK HL more visible from the side as well. This way, you’ll be noticed sooner and stay safer on the road.

INSTALLATION

With the included universal helmet mount, you can quickly attach the BUSTER 900 LINK HL to standard bike helmets without tools. Thanks to the quick-release mechanism, the light can be easily installed and removed—without needing to be realigned.

READY FOR ANY WEATHER

Thanks to IPX4 splash protection, the BUSTER 900 LINK HL remains operational even in rain and changing weather conditions.

LONG-LASTING. USB-C.

Up to 14 hours of continuous light in LOW mode and up to 36 hours in DAY FLASH mode provide plenty of power for long rides. The BUSTER 900 LINK HL can be charged via USB-C in under four hours.
