From the Designer

Hi! I’m Brett, part of the Light My Bricks design team. As a NINJAGO fan, lighting up the Fire Knight Mech was an awesome challenge. This set has so much dramatic energy and story packed into it, especially with the dynamic pose of Rusty mid-battle. I really wanted to make the scene pop and echo the fiery power of the Mech clashing with an ancient sea monster. With the right lighting, it feels like a cinematic moment frozen in time.

Lighting Inspiration

The Fire Knight Mech stands tall over a dramatic scene, ready to strike down the ancient sea monster rising from the depths.

To bring the battle to life, I began by installing two Astro Large Warm White Spotlights in the base to shine up and highlight the full display. These cast a natural, warm glow across the structure, illuminating both characters and architectural details.

The Gimon-Ogu sea monster is lit with three Astro Large Cool White lights—two hidden beneath the base using red and blue transparent elements to emulate eerie, underwater lighting, and one beneath the monster’s gaping mouth under a trans-red plate to amplify the sense of danger.

Rusty, the Fire Knight Mech, is the star of the show. His eyes are illuminated with a Large Warm White Astro Light, while his chest lantern glows with an Astro Large Cool White. His fiery staff bursts to life with two Regular Flickering Effect Warm White lights and an additional Astro Large Warm White, all housed inside transparent orange studs. These flicker and pulse just like the fire energy seen in the NINJAGO Legends: Monstrosity animated short.

This build is a perfect pairing with the Guardian Dragon model (#71847), using the exact same components—so if you’re looking to light up both sides of the story, these companion kits make an incredible display together.

Feature Highlights

Flaming Staff with Flicker Effect

One of the most striking features of this lighting setup is the flaming staff carried by Rusty. It uses a combination of two Regular Flickering Warm White lights and one Astro Large Warm White light, carefully installed behind trans-orange studs. This setup replicates the flame-charged look from the animated series and gives the staff a brilliant flickering glow, adding movement and life to the scene. The flicker effect pulses subtly, making it feel like Rusty is mid-battle, ready to unleash his full power.
