What Vehicles Have What Beacons?

Beacon lights are used to communicate caution, authority, or emergency status.
The color and type of beacon depends on the vehicle’s role.

Amber (Yellow) Beacons – Caution & Work Vehicles

Common vehicles:

Tractors and agricultural machinery

Construction trucks and equipment

Tow trucks and recovery vehicles

Utility and maintenance vehicles

Roadwork and traffic control vehicles

What it means:
Slow-moving vehicle, active work, or potential hazard.

This is the most common and widely legal beacon color for civilian and commercial use.

Blue Beacons – Law Enforcement & Authorized Emergency Use

Common vehicles:

Police vehicles

Authorized security or escort vehicles

Certain emergency response units (varies by country)

What it means:
Law enforcement presence or official emergency authority.

⚠️ Civilian use is restricted or illegal in many regions.

Red Beacons – Emergency Response Only

Common vehicles:

Fire engines

Ambulances

Emergency rescue vehicles

What it means:
Immediate emergency response—drivers must yield.

🚫 Almost never legal for civilian or commercial vehicles.

Green Beacons – Specialized or Command Vehicles

Common vehicles (varies by country):

Medical command vehicles

Volunteer emergency responders

Incident commanders

What it means:
Special authority or command role at an incident scene.

Green beacon usage is highly regional and uncommon for general vehicles.

White Beacons – Work Area Illumination (Not Warning)

Common vehicles:

Utility trucks

Service vehicles

Off-road or industrial equipment

What it means:
Illumination of a work area, not a traffic warning signal.

White beacons are usually used in addition to, not instead of, amber beacons.

Red | Fire, ambulance | Emergency response
Green | Medical command (regional) | Specialized authority
White | Utility/service | Work lighting

For agricultural and commercial vehicles, amber beacons are the correct and safest choice in almost all situations.
