What do you think. Does a stationary light house rotate in your head because you are programed to see it rotate.

I don't think so. Separate from changes in intensity, when looking at a lighthouse you can see the beam moving toward and away from you in the imperfections in the glass. There is a constantly changing vector component to the sine-squared amplitude changes.

Not a real lighthouse, a yard lighthouse, or a table top lighthouse. I think a single LED can do this job. Watch the video.
 
The vid worked for me ron.
Good idea that too, I'll remember that idea if the mrs makes another wooden one.

I've watched real ones up and down both coasts, and they all look the same in this regard. From up close, say 0 to 100 yards, I can see the beam approach and retreat. Granted you cannot see that when at sea, but for a model where the observer has a god's-eye view I would think that a simulation of true rotation would be the better effect.

Also, I did watch the video; hence my comment.

In fact AK, unless the atmosphere is really limpid, you can perceive the beam easily. Just a little of fog or dust in suspension (we call that calima) is all what you need. Even when clouds are low, they help in reflecting the light.

A small stepper would make for a simple solution.
 
Using a steeper motor you need a method to connect the light to power and still turn the light 360 degrees.
The electronic approach is the easiest method.
The working schematic I posted works very well and is low in cost.

Yah, I've seen that (didn't know the name). I'm talking about seeing the beam light up the glass surrounding it. At a distance it looks like the single lamp effect being discussed here, but closer in you can see the light circulate inside the room.
