Description
TrafficCraft: Traffic Light Countdown
A client-side Fabric addon for TrafficCraft by MrJulsen. Adds a countdown timer overlay on traffic lights — just like real-world traffic signals with countdown displays.
What it does
This mod renders a 7-segment digital countdown directly on the traffic light itself, showing how many seconds remain until the next phase change. It reads the schedule of each traffic light (or observes it, if controlled remotely) and displays the timer on the appropriate segment:
- Three-section lights — timer on the yellow segment
- Two-section lights (pedestrian) — timer on the currently unlit segment (so it doesn't blend with the active light)
- Single-section lights — no timer
The digits are color-coded to match the currently active signal (red or green), and are hidden entirely during yellow transition phases, since they're too short to be useful.
Why you should install it
- Makes intersections more realistic and immersive
- Helps players (and traffic!) know exactly when the light will change
- Zero configuration — works out of the box with any existing TrafficCraft setup
- Client-side only — no need to install on servers, works in vanilla multiplayer
- Supports Traffic Light Controllers — the addon automatically learns the phase timing by watching the light for 1-2 full cycles
- Handles edge cases: shows a blinking
-- --when the game is paused, blinks99for overly long phases
Requirements
You must have all of the following installed:
- Minecraft 1.20.1
- Fabric Loader 0.15+
- Fabric API
- Architectury API (Fabric)
- Forge Config API Port (Fabric)
- DragonLib (Fabric, 1.20.1)
- TrafficCraft 1.2.0-beta.3+ (Fabric)
Important notes
- The timer only appears when the light is running on a schedule (either its own or a controller's).
- For lights controlled by a Traffic Light Controller, the timer will not appear immediately — the addon needs to observe 1-2 full cycles to learn the phase durations. After that, it works normally.
- Phases shorter than 3 seconds (like standard yellow) intentionally show no timer.
- This mod does not modify any TrafficCraft blocks or gameplay — it only adds a visual overlay.
Compatibility
- ✅ Works in singleplayer and multiplayer
- ✅ Server does not need this mod
- ✅ Works with all traffic light variants and configurations
- ✅ Works with Traffic Light Controllers
Credits
- MrJulsen — creator of TrafficCraft and DragonLib, without which this addon wouldn't exist
- Design inspired by real-world traffic signal countdown timers

Yellow phase — no timer shown No timer during yellow — the addon hides the countdown for short transition phases where a timer would be useless. -
Synchronized countdown across an intersection Timers synchronized across multiple traffic lights on the same intersection — controlled by a single Traffic Light Controller. -
Pedestrian and car light countdowns Pedestrian light with countdown on the unlit segment, and a matching car light timer in the background. Both learn phase timing automatically when controlled remotely. -
Timer on the unlit segment of a pedestrian light Two-section pedestrian light — the timer appears on the currently unlit segment, so it never blends with the active signal.
