Start Lights

About this app

Start Lights turns any phone into a standardized start-light tree for Mini 4WD racing — the same randomized-hold fairness system racers know from real motorsport, in your pocket.

No two starts are the same. After the staging lights come on, the hold before "go" is drawn randomly every single run, so nobody can jump on rhythm. It's the same principle F1 uses: lights out, and away we go.

★ FEATURES

• Randomized fair start — staging lights fire on a fixed rhythm, then a random hold (configurable range, minimum 0.5s) before go. Impossible to memorize.
• F1-style lights-out signal — the start is bulbs going dark, not a green flash, exactly like a real light tree.
• 14 housing skins — F1 gantry, drag strip tree, karting pod, retro steel, sci-fi, racer livery, neon, vintage wood, carbon fiber, gold star, hazard tape, champion trophy, 8-bit, and circuit board. Pick one and the whole screen quietly picks up its color.
• 6 light color palettes — classic red/green, amber, arctic, ultraviolet, magenta, and pure white, for different venue lighting or accessibility needs.
• 4 sound packs — Classic, Air Horn, Buzzer, and F1 Beep, synthesized cues for staging ticks and the go signal.
• Auto-arm countdown (solo mode) — set a 3/5/10 second delay after arming so the operator has time to get to the start line and race too.
• Bluetooth remote support — pair a cheap camera-shutter remote as a wireless start button. Arm from idle, reset from go, one press each.
• Configurable timing — number of staging lights, staging interval, and hold range are all adjustable within safe fairness limits.
• Landscape-locked, distraction-free — built to be propped up at the start line and read at a glance.

★ WHO IT'S FOR

• Mini 4WD race organizers running heats at a hobby shop or club event
• Anyone who wants a fair, tamper-proof start signal without building hardware
• Solo practice with the auto-arm countdown

★ HOW IT WORKS

1. Prop the phone at the start line in landscape
2. Arm the sequence (or use a Bluetooth shutter remote)
3. Watch staging lights, then the random hold, then lights-out — go
