Video Demonstration for Assembly Square #10255


The LEGO Assembly Square (10255) marks the 10th Anniversary of the ever-popular LEGO Modular Building Series. Spanning over 48 LEGO studs in width and at 4,002 pieces, Assembly Square is the widest and largest modular ever released!

To commemorate this LEGO building milestone, we’ve released our Light My Bricks LEGO light kit packed full of lighting features that will be sure to delight and surprise collectors and fan’s alike.

We have gone to great lengths to ensure all the details, whether big or small have been captured with this light up LEGO kit. The buzzing sidewalk of Assembly Square features charming buildings such as a cafe, florist and bakery. All these have been illuminated with our LEGO compatible LED lights to bring out the vibrant and dynamic features of this LEGO set.

On top of LEGO street lights (using our signature Lamp Post light), we’ve ensured other unique features get the Light My Bricks lighting treatment! Some of the great lighting effects added include a water fountain made to look like running water, flaming bbq grill with realistic fire effects and a whole lot more!

Turn your Assembly Square into a vibrant community hub by adding our custom fully-functional LEGO lights and watch this charming set come to life with lights.
