For Applications not requiring colored lights or Wig-Wag Nightsun continues to offer the Team Issue, a simple and solid dual beam bike light. The Nightsun Team Issue features a dual-beam configuration utilizing two gas-filled lamps, each with its own precision-focused reflector. When high-speed descents demand maximum intensity, a flick of a switch augments the flood beam with a 20 watt high-beam spot light, for a bright 30 watt high-beam output. For maximum runtime, the Nightsun utilizes a high-capacity, 30 watt-hour NiCad water bottle battery for up to 3 hours of illumination per charge.
