The Sigma Buster 1600 Fl front light shines with two Osram LEDs and a dual lens that distributes light evenly over a distance of up to 205 m. Its output reaches 1,600 lm, and the six lighting modes cover a range of riding conditions. The memory function retains the last setting, while the indicator shows the battery level and charging progress.

The light charges via USB-C in 3 hours and can be charged while in use with a power bank. The mount attaches to the handlebar with a screw and rubber inserts, offers three-dimensional adjustment, and features a quick-release mechanism. The logo on the sides acts as a light guide, improving side visibility.
