A proven light system with a separate battery will usually weigh between 450g and 700g. With all the weight in one place it leaves the bike tidy with no battery, leads and cables getting muddy but you may ask the question of how secure it is on the bars. Exposure got it right from the start and their quick release aluminium bar mount has needed very little development. Small and sturdy, it holds the Six Pack light steady and leaves little clutter on the bars when the light is not in use. An updated bracket to fit 35/31.8mm bar clamp diameters, is now available.

‘It’s a dedicated handlebar mounted system in a clean and simple design with a low overall weight’

The Six Pack is programmable using just main switch and the settings chart etched onto the light’s body. You can choose between settings using the low/medium/high outputs, with varying burn times or one of the Reflex settings.

Reflex setting? This technology enables the Exposure light to intelligently adjust its own brightness to suit your riding. A combination of gradient, acceleration and cornering forces are interpreted to match output to your need for light while automatically maintaining the burn time you have selected. The digital OLED status display (OSD) confirms the mode you have selected and shows the remaining burn time in each of the light settings. A full charge from empty is three hours.
