Troubleshooting: Common issues when installing Light My Bricks lighting kits

The individual components used in Light My Bricks light kits are very small and as a result, can easily damage if not handled appropriately. It is very important that the user guides section “Important things to note” is carefully read and followed as doing so will prevent faults and damages to Light My Bricks components.

Most of you who are reading this may have already run into an issue where the lights you’ve installed simply won’t work and you’re trying to figure out why.

First, let’s take you through some of the most common causes:


Check your Batteries

Ensure that use new batteries and that they are inserted the correct way into the battery pack. Check that the ‘+’ side of the battery is facing the ‘+’ side of the battery pack, the ‘-’ side of the battery is facing the ‘-’ side of the battery pack.

For Round Battery Packs, ensure both CR2032 batteries are facing ‘-’ side down.


Ensure there are no obvious breakage in any of the wires or components

Light My Bricks components are very small, if not tiny, and can therefore easily damage when not handled appropriately. Be careful when you remove and unpack components out of the packaging to ensure you do not forcefully pull the wires as this can damage the tiny wires soldered onto the LED. If it’s broken, it will not work.


Expansion board fault

One of the most common problems customers face when installing Light My Bricks lighting kits is with a ‘suspected’ faulty expansion board. Connectors can only be inserted to the expansion board one way, with the exposed wires facing the ‘=’ symbol. Forcefully inserting the incorrect way will damage the pins inside each of the ports on the expansion board. Not only will a light connected to the damage port not work, but if the pins inside the port are bent to a point they are touching each other, it can result in overheating of the wires connected.

If you suspect you have a faulty expansion board then try the following steps to easily fix and resolve this issue:

If you look carefully inside each of the ports, they each contain 2 small pins which are straight. You will be able to identify the faulty port as the port with a bent pin(s).

To fix the faulty port, you will require a sharp object such as a pin, needle or a pair of tweezers which can be used to straighten the bent pin inside the faulty port. Simply use the object to bend the pin back in line. Once the pin is straight, your expansion board should now function correctly.
