traffic adviser

The traffic adviser (also known as the arrow stick or directional board) is used to direct traffic around the vehicle. It has three positions: left, center, and right.

Usage

Action	Default Key	Config Key
Arrow Left	NUMPAD 4	directLinks
Arrow Center	NUMPAD 5	directCenter
Arrow Right	NUMPAD 6	directRechts

Each button works as a toggle: press once to activate, press again to deactivate.

Configuration

directLinks = {3, 4},     -- Extras for left-pointing arrow
directCenter = {5, 6},    -- Extras for center pattern
directRechts = {7, 8},    -- Extras for right-pointing arrow

Exclusive / Unique Groups

Traffic adviser directions are typically configured as unique groups — meaning activating one direction automatically deactivates the others. This is handled via the unique property:

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

When unique is configured, activating directLinks will first turn off any active extras from directRechts and directCenter, ensuring only one direction is active at a time. See Unique / Exclusive Extras for more details.

You don't have to limit unique groups to just the traffic adviser. Any combination of light types can be made mutually exclusive using the unique property.
