The Sigma Buster 1100 + Sigma RL150 light set is made up of the Sigma Buster 1100 lumens front light and the Sigma RL 150 thanks to the powerful 1100 lumens and a 165m beam, this new power guarantees that the streets and paths are perfectly illuminated. With six light modes and a battery life of up to 50 hours, no night ride can be long enough. The BUSTER 1100 is available in two versions: One can be mounted on the handlebar and one can be mounted on the helmet (HL). The powerful sports light beam makes it perfect for night rides on a road bike, gravel bike or MTB.
