3D Mechanical Puzzle Lighthouse

This mechanical 3D puzzle presents a lighthouse model inspired by maritime signaling and safety at sea. The compact model depicts an automated lighthouse serving as a navigation point for ships at night or in difficult conditions. It consists of three main modules: a base with a reduction motor and planetary gear system, a central section with mechanical transmission, and an upper light chamber that creates a spiral light effect. A rotating radar in the central section simulates scanning the surroundings and two-way signal transmission. Five moving elements are powered by an internal gear mechanism, producing continuous movement throughout the model. Clear instructions and numbered parts make assembly accessible to older children and adult fans of models and technology. The model is part of the Industrial City series, whose models can be connected to create a moving mechanical city. It has 60 pieces, takes about an hour to assemble, includes a display stand, is powered via USB, and develops logical and motor skills, patience and spatial thinking. It can serve as a gift or distinctive decoration.
