The Exposure Joystick Mk8 with Red Eye combines a bright 400 Lumens front light with a rear light (Red Eye), in one nifty package. Optimized Mode Selector (OMS) allows you to easily select from a concise number of programs to provide the optimum lighting for your ride. OMS programs enable you to obtain the lights full potential and optimize the output, up to 400 lumens, and with burn times anywhere from 2-36 hours. The Joystick Mk8 automatically recognizes accessories allowing you to power additional front and rear lights, use the remote Switch, charge USB devices on the move or plug in a support battery for extended light. A primary feature unique to Exposure Lights removes the hassle of cables and straps, making the light completely self-contained. Includes helmet mount, Red Eye rear light and smart charger. 87 g.
