To build a drag racing tree, you'll need a timing system, lights, and a control mechanism. Start by setting up a series of lights in a vertical configuration, typically consisting of red, yellow, and green lights for each lane. Use an electronic timing system to control the lights: the red lights indicate a false start, the yellow lights signal the countdown, and the green lights signal go. Ensure the system is calibrated correctly for accurate timing and fairness in racing.
Caution lights.
