VIDEO DEMONSTRATION

Description

Operating undetected from Muggle's knowledge, Diagon Alley is a bustling high street catering for wizards and witches with wares to make potions or stock on up spell crafting necessities like cauldrons, brooms and wands.

Consisting of 4 "doll-house" like buildings, Diagon Alley will thrill and delight Harry Potter fans - but the true magic of this LEGO set is realised when it is coupled with the Light My Bricks light kit that truly brings this enchanting set to life!

With the ability to arrange and connect the separate buildings anyway you like without compromising the lights, the Light My Bricks light kit gives you the flexibility to display Diagon Alley however you like, and at the same time, enhance all the unique features this set has to offer.

Using film frames as reference, the design was continually iterated and innovated to ensure the lighting and atmosphere was as true to the film as possible.

With 74 individual lights, including internal and external lighting, the Light My Bricks will put a spell on your Diagon Alley and make it a true centrepiece to marvel at.

Important Note

This lighting kit is powered by a USB Power Bank or USB Power Adaptor (to connect to a mains outlet), which is NOT included in this kit. If you do not have a USB Power Bank, you can purchase them from our Powering section.

Fun to build and looks amazing

I use the display of the set as a light source in my living room. Lights are the right colors (not too bright)

Fantastic light kit!

The Diagonal Ally light kit really adds dimension to the Lego set and helps bring it to life. The only negative I have is that some of the photographs in the installation guide are out of focus making it difficult to see where to hide wires.
