Here we have a pair of red and green clip on boat navigation lights. These extremely bright Leds clamp on to any 1"-1.5" rail. They have 3 modes, on, strobe and fast strobe. They run on 2 button cell batteries which are included.

These are great for boats/kayaks/canoes without a battery or to keep on board in case of an emergency. If your standard bow lights are not Leds, these should be much brighter. Feel free to ask me any questions. Package includes 2 lights, one red and one green.
