Mount the red Visibility Light on the left or port side and the green Visibility Light on the right or starboard side. If an approaching watercraft sees the green light, they know that they have the right of way. If the approaching watercraft sees the red light, they know that your watercraft has the right away. The thin, waterproof strips feature six ultra-bright LEDs. Cables and complete mounting instructions are included. Visibility lights are equipped with double insulated wiring. Low current draw, 50-70 mAs per light. Sold in packs of two: 1 red, 1 green strip per pack.
