LED Light Kit | Set #21355 | The Evolution of STEM

Why You'll Love It!

This LED light kit adds a glowing finish to the LEGO® The Evolution of STEM set #21355, designed for builders who want a completed model to look striking after the room lights go down. LEGO® display builders and collectors will appreciate how it adds night-time presence to a model they have already built.

Key Features:

• Fits Built Sets: Made for assembled models, this kit asks for a little refitting and lets you add light to the LEGO® The Evolution of STEM set #21355 without a rebuild.
• Beginner Friendly: No circuit experience is needed, because the kit comes with simple step-by-step instructions that guide you through placing every light and routing every cable.
• Concealed Wiring: A twisted pair wire design balances durability with discreet installation, helping the cables stay tucked out of sight so the lit model still looks clean on display.
• What You Get: Connecting cables, lights, expansion boards and related parts are part of the kit, giving you the main lighting components together in a single set for installation.
• Power Supply: The kit includes a battery box to power the lights, and the batteries themselves are not included, so you will need to supply your own to get started.
• Digital Guide: The step-by-step instructions come as a PDF, making it easy to zoom in on details and keep the guidance close while you work on the model.
• ABS Plastic Material: Made from eco-friendly ABS plastic, the kit is described as compatible with LEGO® sets and is intended to blend into the model once it has been installed.
