When the paint is dry, glue the pieces of your light house and tower together, and assemble the LED, the platform below the light and the lighthouse tower.
Glue the tower and building to the finished base and use a piece of masking tape or glue a piece of paper to the base to hold the wires up in the channel under the base. The masking tape or paper will finish the underside of the light and help protect any table surface the light may stand on.
If you are using a battery to power the LED, test the contacts by holding them against the battery terminals. If it doesn't work, change which wire is against the terminal, you may have the wires reversed and LED's are polarized and will only work with wiring running in one direction. When you are sure the light is operational, attach the LED wires to the battery cap (lengthen them if necessary) and place the battery assembly out of site in a trunk or chest of drawers in the scene, or on the back of the roombox or scene.
If you are not using a battery to power the light, attach it to a plug which fits your dolls house or roombox wiring, or wire it into your lighting system.
