The Light My Bricks Micro Bit Lights are tiny, miniature LEDs with very thin wires. The LED, measuring less than 1 mm, fits between almost any LEGO brick. This allows even the smallest pieces to be equipped with these Bit Lights, elegantly illuminating your LEGO creations. These white Micro Bit Lights come in a pack of four. Each LED is attached to a 15 cm long brown and black cable with a micro connector. The Micro Bit Lights connect to the Light My Bricks Micro Expansion Board, which can then be connected to the rest of your chosen lighting circuit. Light My Bricks offers LEGO fans an easy way to enhance their LEGO models with LED lights. All Light My Bricks components are plug-and-play compatible – no electronics knowledge is required for installation. Light My Bricks parts are small and delicate enough to fit between and under LEGO bricks. LEGO is a trademark of the LEGO Group.
