Lego debuts Smart 2x4 Brick with light, sound and sensors at CES

At CES, Lego revealed a new Smart Brick — a 2x4 piece packing light, sound and sensor-based interactivity powered by on-board silicon, designed to work with traditional builds without introducing screens. The company said the module will debut in its Star Wars line, bringing discreet effects and responsive behaviors to familiar sets while preserving the tactile play experience collectors and parents value.

The launch marks a clear step into embedded hardware for Lego, signaling investment in electronics that complement rather than replace physical bricks. The move could broaden appeal for play and display use-cases and is likely to draw attention from investors tracking BRICK. Observers will watch whether this creates a wider ecosystem of smart elements across future themes and licensing partnerships.
