Lighthouses are towers with elaborate lighting at the top, usually redstone lamps that are turned on and off to give the impression of a rotating light. If a tower is built with a taper or is slender all the way up that results in a cramped space for placing redstone.
Here is a scheme for controlling 3X3 lamp panels in a 5x5 area using sticky pistons with slime blocks to push a redstone block into position. Obsidian or other non-movable is block is necessary because of the slime blocks, and to prevent the sticky pistons from powering themselves from the redstone block 2 slimeblocks are used on each piston to keep a minimum distance. A sequence of 4 pics (not a video).
The repeaters powering the lamps are set to max delay to stop the lamps from flickering, which also reduces Minecraft lighting engine rendering lag.
The last pic shows how the pistons are controlled, just a loop of max delay repeaters.
