Frequently Asked Questions (FAQ) - Light Up Your World!

Are Bright My Bricks kits safe for my LEGO® set?

Your peace of mind and the preservation of your bricks are our highest priorities. We exclusively use a low-voltage (5V) system with high-quality micro LEDs that do not generate heat.

 

This ensures your LEGO® pieces will never melt, warp, or be damaged. All our components are thoroughly tested and comply with strict international safety standards, making them completely safe for any build.

Do I need any special skills or tools to install the kit?

Not at all! If you can build a LEGO® set, you have all the skills you need. Our kits are designed as a "Plug and Play" solution, requiring no soldering or complex electronics knowledge

 

Every kit comes with a detailed, step-by-step instruction manual filled with clear, high-resolution photos to guide you. It's a fun and rewarding new way to experience your favorite set.

How are the wires hidden? Will they be visible?

We have meticulously designed our kits to be as discreet as possible. Our connecting wires are exceptionally thin yet durable, allowing them to fit perfectly between and under LEGO® bricks without affecting the connection or "clutch power." 

 

Once installed according to the instructions, the wiring is virtually invisible, ensuring the original aesthetic of your model is fully preserved.

What technology is used for your lights? Are they safe?

Your safety and the preservation of your bricks are our absolute priorities. We use high-quality, low-voltage (5V) micro-LEDs that do not heat up and therefore will not risk damaging your precious LEGO® pieces. 

 

All our components are rigorously tested to meet international safety standards. Power is supplied via USB or a battery pack, offering a safe and flexible solution.

Do I have to completely dismantle my LEGO® set to install the kit?

In most cases, no. Our installation process is designed to be as minimally invasive as possible. You will generally only need to remove a few pieces or sections of your model to run the wires and place the LEDs. The instructions will tell you precisely which parts are affected.

How are the lighting kits powered?

We offer you flexibility! Each kit can be powered in two ways:

 

By Battery Pack: Ideal for displaying your set anywhere (usually requires 3 AA batteries, not included).

 

By USB: Simply connect the provided USB cable to any USB power source (power bank, wall adapter, computer...). This is the perfect solution for long-term lighting.

 

For optimal and consistent lighting, we recommend using the USB power supply.
