JET's 13W HID Blast is 2x more efficient than JET's 20w halogen light. This energy efficient light makes it a perfect product for those riders needing maximum brightness with long burn times. The HID Blast is ideal for all riding conditions. From city streets to high speed technical rocky descents. It can go anywhere and deliver the visual comfort of daylight like conditions. The canister battery fits cleanly in any water hydration pack. JET's exclusive thread lock cable system delivers vibration, shock, short, and waterproof reliability. Our easy to use aim-as-you-ride helmet mount features JET's patented safety breakaway system. This elegantly designed two piece mount will break apart with a 5lb impact. It can be reassembled in seconds. This feature could be the difference between a neck injury and no injury at all in the event of a fall or the light catching a low hanging branch. A must have feature.
