BUSTER 400 HL Helmet Lamp

With the compact and lightweight Sigma BUSTER 400 HL helmet light, nothing stands in the way of your night-time road and off-road rides. With its luminous flux of up to 400 lumens and a light range of approx. 120 metres, it illuminates the path in front of you. Equipped with an Osram high-power LED and the converging lens specially developed by SIGMA, you get very even light distribution across the entire field of vision.

Thanks to its five light modes, you can adjust the light intensity of the helmet lamp to suit your individual needs. Whether you need full power for unlit paths or want to be more visible in cloudy weather – the BUSTER 400 HL gives you maximum flexibility. In addition to the three lighting levels, there are also two flashing modes available. Pre-selectable mode profiles ensure that you quickly have the right levels available for you. Even after being switched off, all presets and the last selected lighting level remain stored thanks to the memory function.

Other features of the Sigma Buster 400 HL helmet light include a quick single-click battery check before riding, mode and charge level indicators, and the illuminated Sigma lettering for better side visibility. Of course, the 400 HL is protected against splash water and also can be operated without any problems when wearing gloves. With it, the next night-time after-work ride can come.
