What Is the Start Lights Reaction Test?

The Start Lights Reaction Test is a free online tool built around a race-start light gantry. It measures how quickly you react at the moment the red lights go out and the green appears — the same cue that starts a real race.Three rows of red lights light up one row at a time, building anticipation. After an unpredictable hold they cut out and the bottom row turns green, and you click or tap as fast as you can.

Why Test Your Reaction Time?

Understanding your reaction time can help you improve your performance in various activities.

How Does the Start Lights Reaction Test Work?

Here is exactly how the test runs:1.Light Sequence: Three rows of red lights illuminate one row at a time at 500-millisecond intervals, cascading down the gantry.2.Random Hold: Once all three red rows are lit, the lights hold for a random 0.5 to 2.5 seconds.
