Small And Lightweight Bicycle Safety Light

Out of the many uses for the MJ-900B, one of them is as a super small and lightweight bicycle safety light. At 42g it hardly adds to the weight on the handlebars, external 2 cell battery pack is strapped to your down tube to provide the single XM-L2 with 2.2 hours of constant runtime at the highest brightness.

The warning flash feature unique to the Bluetooth line is a very useful tool to get yourself noticed among busy city traffic. Fast flashes in quick successions at full brightness will ensure you are seen from a couple of miles away by fast moving motorists. However in the city traffic you might want to tune it down to only a couple dozen lumens. 

Thanks to the freely adjustable Bluetooth app, from lighting modes to brightness can easily modified from your mobile devices. Whether you want to use the MJ-900B as a helmet light or on your handlebar or even on your seat post as a rear warning light. The customization options are there to make it possible. 

The 900B can also be used on the mountain trails if you so choose, at 1000 lumen output, you might find it quite adequate for less technical trails. The helmet light option is also there with an option accessory MJ-6058. The battery pack can also be used to charge other USB compatible devices in times of need.
