This Light My Bricks 2.0 LEGO lighting kit contains everything you need to add lights to your LEGO 76419 set. You don't need a letter from Hogwarts to enter the School of Witchcraft and Wizardry. But you do need Light My Bricks. Make magic happen when you combine this LEGO lighting set with your Harry Potter Hogwarts castle and grounds. With 14 individual LEDs illuminating every detail of the Wizarding World's most iconic location, anyone who takes a look is guaranteed to be enchanted. As if by magic, 4 Astro LEDs can be skilfully placed throughout the set to cast moonlight over the castle, the Black Lake and the Durmstrang ship. More Astro LEDs light up the castle bridge, cast an eerie shadow over the Whomping Willow and bathe the entire castle grounds in a warm glow, bringing the School of Witchcraft and Wizardry to life. And Light my Bricks haven't forgotten other details such as Hagrid's hut, the Chamber of Secrets and Professor Snape's Potions Room - everything is illuminated to draw your eyes to the most iconic details of the display. Remember, happiness can always be found, but only if you remember to switch on the LEGO lights.
