A Illuminating Addition: Review of the Light Kit for Crocodile Locomotive 10277 by Game of Bricks

Introduction: The Crocodile Locomotive 10277 from LEGO is a thing of beauty, a masterpiece that's as satisfying to assemble as it is to display. However, Game of Bricks, a renowned third-party company, has decided to add a little more spectacle to this set. They've developed a light kit, designed specifically for the Crocodile Locomotive, promising to bring this impressive model to life in a whole new way. But does it deliver on this promise? Let's find out.

Light Kit for Crocodile Locomotive 10277

Easy Installation

Firstly, we need to talk about the installation. Even if you're a newbie in the realm of LEGO lighting, there's no need to fear. The light kit comes with an instruction manual that's clear, concise, and easy to follow. The creators have gone to great lengths to ensure that the integration of the lights is as smooth as the original LEGO building process itself. No advanced technical skills are required; all you need is a little patience and careful attention to the guide.

Enhanced Details: 

Once installed, the effects are instantly noticeable. The Crocodile Locomotive doesn't just sit on your shelf; it comes alive. The lights are strategically placed to highlight the most intricate details of the LEGO build, casting shadows and creating an ambiance that transforms the locomotive from a static display piece into a living, breathing spectacle of light and shadow. The engine glows with a warm, inviting light, while the train's windows are illuminated, suggesting a vibrant life inside.


One of the standout features of the Game of Bricks light kit is the level of customization it offers. You're not just stuck with a single, static lighting option. The kit includes several different colors and modes, allowing you to change the look and feel of your Crocodile Locomotive at a moment's notice. You can set the mood according to your liking, a feature that adds an extra layer of fun and creativity to your LEGO building experience.


Despite their delicate appearance, the lights are surprisingly durable. They are designed to be flexed, twisted, and threaded through the LEGO bricks, meaning they're robust enough to withstand typical handling during installation. The connecting wires are thin but sturdy, ensuring the longevity of the lights. Also, the power supply is efficient and reliable, providing a steady flow of energy to keep your locomotive lit up for as long as you need.

Minor Downsides: 

Of course, no product is without its flaws, and the light kit from Game of Bricks is no exception. The most notable issue is the power supply's external placement, which can be slightly distracting from the overall display. Also, the tiny size of the LED lights can make installation a bit fiddly, especially for those with larger hands. However, these are minor inconveniences that do not detract significantly from the overall experience.

While it has a few minor downsides, they are far outweighed by the sheer joy of seeing your Crocodile Locomotive come alive in a wash of light and color. The Game of Bricks has indeed delivered on its promise, turning an already great product into something truly magical.
