How to run the test
- Click once when you are ready
- Wait while all five red lights illuminate
- React the instant every light goes out
- Complete five valid starts for an average
MOTORSPORT / LIGHTS OUT
F1 Reaction Test
Watch the five red lights illuminate, then react only when every light goes out. The final result averages five valid starts.

Why the delay is randomized
A fixed delay rewards anticipation instead of visual reaction. This test varies the fully-lit hold time on every start and rejects early clicks.
The sequence itself provides context, while the measured interval begins only at lights out.
Understanding your time
Under 150 ms is labeled exceptional, 150–199 ms excellent, 200–249 ms average, and 250 ms or more as a training opportunity. These are intentionally simple reference bands.
- Use the five-run average, not one lucky start
- Compare results on the same display and input device
- Rest between repeated sets to avoid anticipation

QUICK ANSWERS
Frequently asked questions
When should I click?
Wait until all five red lights switch off. Clicking while the lights are illuminating or while all five remain red counts as a false start and is not scored.
Is the lights-out delay always the same?
No. After all five lights are illuminated, the delay is randomized from run to run so timing the sequence is not a reliable strategy.
Is this an official Formula 1 test?
No. It is an independent browser reaction game inspired by a five-light motorsport start sequence and is not affiliated with Formula 1.
