Attaching anything to the top of the pole other than a small flag or
streamer is a bad idea because it will tend to make the pole top
heavy.

That's one of the reasons I'm building my own. I've spent a lifetime
making things float upright

I want the light at the top. The swimmer with his eye one inch above
sea level is going to have a hard time getting to a floating light.
