Boat and kayak owners, these JAYOBGO LED marine lights are essential for safe nighttime water activities! The 12-piece set includes 6 red and 6 green lights - exactly what you need for proper navigation lighting that makes your vessel legal and visible after dark. The water-resistant design means you don't have to worry about rain or splashes damaging them, though they're not meant for complete submersion. Each light features three modes - steady lighting, flash, and slow flash - giving you flexibility depending on conditions and battery conservation needs. The installation couldn't be easier thanks to the flexible silicone body and double hook design that lets you attach them anywhere in seconds without tools. They're powered by included CR2032 batteries that provide impressive runtime - 35 hours in steady mode and up to 160 hours in flashing modes! The brightness is seriously impressive too, with visibility extending more than 0.6 miles to ensure other boaters can see you clearly. I've used these for everything from kayak fishing trips to sailboat racing, and they've been reliable every time. The compact size makes them easy to store when not in use, and the durability means they'll last through multiple seasons. Your nighttime water safety just got a major upgrade with these affordable, effective navigation lights!
