Note: While it is possible to create a similar effect with standard blinking bulbs (not LEDs) or a mixture of red and clear bulbs commonly sold for dollhouse fires, fires powered by regular bulbs give off too much heat to allow them to be set behind a fireplace grate under a mantel, or inside a doll’s house cooking range. You can also make the lighthouses without a working bulb, or make several without a working bulb along with one working unit to set in a dolls house shop display.
