Cygolite's Streak 310/Hotshot 2W SL Combo Light Set puts versatility, power, and loads of light in a tiny package. Up front, the 310 lumen Streak 310 headlight gives you plenty of light for commuting and road rides. It features a unique SteadyPulse mode that alerts night time motorists with pulses of light while still constantly lighting your path and a DayLightning mode that creates super-visible flashes for enhanced visibility during the day. Out back, the Hotshot SL uses a powerful 2-watt LED with a custom reflector to blast four flashing modes and one steady mode for excellent visibility. Both lights are USB-rechargeable, and the combo includes a charging cable and handlebar and seatpost mounts.
