Functional LEGO Traffic Signal
A fully-operational LEGO traffic signal lamp which uses powerful LED spotlights and a circuit board from a model railroad! To build your own version of this project, simply refer to my Instructables tutorial:

The output uses the same principle as my mosaic Super Mario lamps (Technic bricks + transparent plates), and uses the LEGO structure to house the delicate electronic parts.
