I have some LED pole lights coming for my boat. They are for inside the

Could I put them on a rheostat so that I could dim them down?

Buy an electronic control from China on eBay. Costs just about
nothing.

But he wants to run it from DC on the boat, not 60 Hz AC, so I
think that the light dimmers (if that is what you are suggesting) won't
work without first converting to AC.

If it has an internal power supply then nothing short of radical surgery
will work.

LEDs themselves are current operated devices, not so much voltage.
So reducing the current flowing through them will cause them to dim.

But with an internal supply (and I'd suspect solar powered means just
that) - nope...
