Light your way and be seen with Sigma's Eloy/Cuberider combo. In front, the Eloy has four super bright white LEDs, is visible from the side, and sports a long run time of up to 100 hours. Add the Cuberider rear light with its four LEDs as well as run times of up to 40 hours and you'll be all set for nighttime commuting. Both lights let you choose between steady and flashing modes with a convenient click switch. And, lightning-quick installs are assured thanks to the tool-free installation. Plus, batteries for both lights are included.
