Brickstuff Power Supply for LEGO 9V Trains (Non-Directional Output) - SEED09V
SEED9V: LEGO 9v Power Source
As requested by our LEGO® 9V train customers, here is a simple and easy-to-use power supply that works with the older 9V train power packs and train motors. Use it to add lights to any LEGO® 9V train, or use it directly connected to the LEGO® 9V train speed regulator to power your Brickstuff lights.
NOTE: this product is compatible with the older line of LEGO® 9V trains. It is not intended for use with the newer Power Functions system.
This power supply is non-directional, meaning it supplies power to its connected lights when a train is moving forward or backward. Because of the way the LEGO® 9V power system works, the lights are off when a train is stopped.
