Lights Out: Reaction Time Test

Five red lights. One blackout. How fast are you really? Lights Out is a reaction time test built around the starting lights used in real motorsport. Wait for the five lights to come on, hold your nerve through a random delay, then tap the instant they go out. Your reaction time is measured to the millisecond and ranked against the drivers who do this for a living. HOW FAST ARE THE PROS? Top grand prix drivers launch in under 0.200s. The fastest recorded start is 0.201s. Drag racers at the top level react in 0.039s. Usain Bolt left the blocks in under 120ms. The average person? About 250ms. Think you can beat that? Find out in about ten seconds. FOUR WAYS TO PLAY Launch Sequence — the classic race start. Five lights build, a random hold, then blackout. Millisecond timing, false start detection, and a direct comparison against real driver benchmarks. Reaction Grid — a 3x3, 4x4 or 5x5 grid of targets that light up one at a time. Untimed mode measures precision and accuracy. Timed mode gives you ten seconds. Six separate leaderboards cover every mode and grid size combination. Pit Lane — two modes in one. Endurance is a daily colour-matching rhythm challenge: catch the tyres matching the day's target colour, dodge the rest. The pattern is identical worldwide each day, so your score is directly comparable with everyone else's. Circuit is a 500-level campaign across five racing eras, with twenty grand prix circuits per era, boss levels every 25 stages, and qualifying bonus rounds. Two Player — split screen, head to head, same device. The screen divides in half and the fastest finger wins. TRAIN YOUR REFLEXES This is a reflex trainer as much as a game. Every run is recorded, so you can watch your reaction time improve: best time, rolling average, consistency score, and a full history of every attempt. Daily streaks keep you honest, and motorsport fun facts give you something to think about between runs. COMPETE Global leaderboards for every mode, with all-time and weekly boards so newcomers always have something to chase. Bronze through Diamond tier badges mark your rank. Player profiles show your best time, streak and avatar. Achievements track the milestones along the way. MAKE IT YOURS Eleven racing team colour themes and seven visual styles, from clean modern through cyberpunk neon, hand-drawn sketchbook, and a pixel-perfect retro desktop. Custom app icons. A home screen widget showing your fastest time and current streak. PIT PASS Climb the tier ladder each season for cosmetics, tyre skins, lane backgrounds, profile flair and bonus currency. Season 1, Monaco Night, is wet asphalt and neon reflections. FAIR BY DESIGN Free to download with every game mode fully playable. No paywalls, no energy timers, no gates on gameplay. Advertising is light and optional extras are exactly that. Available in 24 languages. Lights out, and away we go.
