We understand lights are an integral part of your daily commute. Using a light can mean the difference between being seen or not by automobile drivers. Many of the "entry level" commuter lights are nothing more than "be seen" lights. Your overall safety and visibility should not be limited by your budget, and that's why we created the Mako Series. The Mako line offers four models and up to 250 lumens, not only allowing the cyclist to be seen but allowing the cyclist to see as well. The Mako line is easy on the wallet and easy to operate. For much of night riding, the key to survival is not only seeing but also being seen, the CherryBomb 100 addresses the latter. By incorporating a unique multi-directional collimator specifically designed for cycling, the CherryBomb 100 maximizes visibility by dispersing light to the sides of the rider as well as to the rear, effectively eliminating blind spots to upcoming automobiles. To further rider safety and visibility, the CherryBomb 100 employs a custom-made, built-in reflector which allows the rider to be night time visible even when the taillight is in the off position. Clip and bike mounts are included, for flexible mounting options. Mako 250 - Low cost, high powered light - Highly visible in traffic = keeps you safe - Run Time: 7:00 – 28:00 hours - 3 light settings—High, Low, and Flash - Tough durable design - Water / Dust Resistant IP64 Rated CherryBomb 100 - Daylight Visible Flash (DVF) - Up to 136 hour run time - Visible up to 1 mile - Internal reflector = visible if light in off mode - Easy to operate AAA batteries - Super bright day time flash mode - Be Seen by cars = Be Safe - Water / Dust Resistant IP64 Rated
