Here is one that is designed for the type of socket you now have. Maybe you could use this and find a fixture that could be adapted to use the existing socket.

If this does not work, and if you can't find something else wireless, putting in regular switches would not be too hard, and it might make for a more permanent and durable installation.

Thanks for the tips ky114.

I will look into the possibilities of using the wireless socket and also consider hard wiring.

Do you have attic access above? Because it's trivially easy to run an actual switch if you do.

I do, but I have about 20" of blown in cellulose insulation that I would have to walk across to get to the areas and then move aside to do the wiring. It is possible, but I would prefer a reliable, less messy way.

There are a number of solutions available. I have a wireless ceiling fan controller that would work...but have all the fan controls which you wouldn't have. Homer's, Lowes, Ace, has them. Then there's X10. I'm sure you will come up with a good solution that fits.

Another suggestion would be motion sensing light fixtures.

I had not thougt of a motion sensing fixture. That is a good suggestion and I will seriously consider that.

I know the best solution would be to hard wire a switch through the attic and down in the wall, but another idea that has occured to me is Wiremold. The run on the ceilings would be less than 2'. Then the Wiremold would run down along the door frame and then over a few inches to the switch. Other than the ceiling most of it would not be visible looking into the closets.

Any thought on this?
