I am looking for such lights myself, especially ones that can be seen from afar on the water. I think it would be best to ask around in kayaking communities or those who do night swims.

I love going out on a kayak on the lake, especially at sunset. But when it gets dark, visibility is always a concern. I was looking for good lights for navigation and recently came across this selection of navigation lights for kayak. I liked the site, everything is clear, the descriptions are detailed. I haven’t ordered it yet, but my friend bought one of these navigation lights and he praises it non-stop. He says they are very bright, hold up well even in rough water, are not afraid of water and work reliably for hours. I think I’ll order some for my next trip. Moreover, the reviews on them are very positive, and the quality is really up to par.
