In Alabama, vehicle lighting regulations are established to ensure road safety and proper vehicle identification. Below is an overview of the authorized use of colored lights and their respective applications:
Standard Vehicle Lighting
-
Headlights:
- Vehicles must be equipped with at least two but not more than four headlamps, positioned with at least one but not more than two on each side of the front of the vehicle.
- Headlamps must comply with specific mounting height requirements: not more than 54 inches nor less than 24 inches from the ground.
-
Taillights:
- Every motor vehicle, trailer, semitrailer, and pole trailer must have at least one tail lamp mounted on the rear, emitting a red light visible from 500 feet.
- Taillamps should be mounted at a height between 20 and 60 inches.
-
Turn Signals:
- Vehicles may be equipped with lamps or mechanical signal devices capable of clearly indicating any intention to turn either to the right or left, visible from both the front and rear.
- Signal lamps indicating intention to turn must be visible from a distance of 100 feet during both daytime and nighttime.
Restrictions on Colored and Flashing Lights
-
Red Lights:
- Vehicles are prohibited from displaying red lights visible from directly in front of the vehicle, except for authorized emergency vehicles.
-
Flashing Lights:
- Flashing lights are generally prohibited, except for turn signals, hazard warnings, and authorized emergency or service vehicles.
Authorized Use of Colored Lights

Emergency Vehicles:
- Police vehicles may use red or blue lights.
- Fire departments and other authorized emergency vehicles, including ambulances, may use red lights.
-
Mail Delivery Vehicles:
- Vehicles in active service transporting United States mail may display two simultaneously flashing lights with amber lenses to the front and red lenses to the rear, mounted on the highest part of the vehicle.
Aftermarket and Decorative Lighting
-
Underglow Lighting:
- Alabama law does not explicitly permit underglow lighting.
- Therefore, the use of underglow lighting is not authorized and may be considered illegal.
-
Additional Lamps:
- Vehicles may be equipped with up to one spot lamp, two fog lamps, one auxiliary passing lamp, and one auxiliary driving lamp, each subject to specific mounting and usage regulations.
Compliance and Penalties
- Unauthorized use of colored or flashing lights can result in legal penalties, including fines. Vehicle operators must adhere to Alabama statutes regarding vehicle lighting to ensure safety and compliance with the law.
Important Considerations
-
Local Ordinances:
- In addition to state regulations, local municipalities may have specific ordinances governing vehicle lighting. Vehicle operators should be aware of and comply with any local requirements.
-
Legal Consultation:
- Before installing aftermarket lighting, consult Alabama's vehicle equipment regulations or seek legal advice to ensure compliance with state laws.
