I use a collapsible pole made from a swiffer mop and a ski pole tip. The angle lets me press fit into a female opening I’ve mounted on various boats
Try the Guardian Angel lights. They have a variety of methods to attach them to both kayaks or PFDs. They also market different color combinations depending on your needs.
If you are looking for something to identify yourself at night on a kayak, look at the
YakAttack Visipole II light mast, it’ll attach to gear track rail and the kit does come with a mount block.
I use the YakAttack Visipole too. It’s great. I didn’t really want to make permanent modifications to my kayak (a Tarpon 14), so I attached a PVC pipe to the back of my seat with zip ties to use as a light holder. Works great and I like that it’s behind me so doesn’t blind me when I’m paddling at night.
There are rare earth msgnets that have a screw hole center.
that is the main thing. Last thing I would want is a bright white light anywhere near my vision. Putting it behind you is the perfect place for it.
Thats where I put mi Visi-Pole except I put a 4" rail just behind the Cockpit so I could put the spray skirt on on my Tsunami 175.
I use a suction cup type light with a tether on my rear deck and have never had a problem with the suction cup coming loose on a composite hull. It is mounted close enough to me that I could reach it if it came loose. I also have a similar light with a buoyant base that is designed to attach to deck lines or bungees.
In addition I have a PFD light that I will have on mounted on a PFD strap on the back of my shoulder. However, the PFD light, and many like it will not satisfy the USCG requirements because the attachment strap would not allow me to remove and aim it at an approaching boat. I suppose I could put a longer tether on it.
A PFD light or another light that you have on you, as opposed to the boat, can be a lifesaver if you ever become separated from your boat.
Headlights can satisfy the requirements, but they interfere with night vision, blind whoever you look at, and very few are waterproof. I suppose one could be worn facing backwards.
I do not trust power boats in the day time.
