Unique extras

The unique property in vehicle configs allows you to define groups of lighting features that are mutually exclusive — activating one automatically deactivates the others.

Primary Use Case: Traffic Adviser

The most common use is for the traffic adviser, where only one direction should be active at a time:

unique = {
    directLinks = {3, 4},
    directRechts = {5, 6},
    directCenter = {7, 8},
}

With this configuration:

• Activating directLinks → turns off extras {5,6} (directRechts) and {7,8} (directCenter)

• Activating directRechts → turns off extras {3,4} (directLinks) and {7,8} (directCenter)

• Activating directCenter → turns off extras {3,4} (directLinks) and {5,6} (directRechts)

How It Works

1

Step 1

The script checks if the toggled type exists in the unique table.

2

Step 2

For every other type in the same unique table, it turns off all listed extras.

3

Step 3

The UI updates for all deactivated types.

4

Step 4

The requested type is then toggled normally.

Custom Unique Groups

You're not limited to traffic adviser directions. Any combination of light types can be made mutually exclusive:

-- Example: Cruise lights and work lights are mutually exclusive
unique = {
    steadyBlue = {7},
    steadyWhite = {8},
}

With this, activating cruise lights turns off work lights and vice versa.

Important Notes

• The extras listed in the unique groups should match the extras listed in the corresponding light type properties.

• A light type can only be in one unique group.

• The unique property is optional, omit it entirely if you don't need mutually exclusive behavior.
