Georgia Law on Colored Lights: Blue, Red, Amber, and Penalties

Georgia law on colored lights reserves blue, red, and green flashing or revolving lights for law enforcement, emergency, and specifically permitted vehicles. Amber flashing lights are allowed for tow trucks and road service vehicles. Steady white headlights and amber or white accent lighting are generally fine for private vehicles. Violations are misdemeanors that can carry up to $1,000 in fines and up to 12 months in jail under O.C.G.A. 17-10-3, and using blue lights while committing a felony carries a mandatory minimum $1,000 fine and one year in prison. The main rules sit in O.C.G.A. 40-8-90 through 40-8-96, with amber-light rules in 40-8-35.

Blue Lights Are the Strictest

Blue is the most heavily restricted color. Under O.C.G.A. 40-8-90, it is illegal to operate any vehicle equipped with a device capable of producing blue light, whether the light is flashing, blinking, revolving, or steady. Simply having a device that can emit blue light inside the vehicle is enough to violate the statute.¹

Three exceptions exist:

Motor vehicles owned or leased by any federal, state, or local law enforcement agency.
Vehicles issued a specific state permit authorizing blue lights.
Antique, hobby, or special interest vehicles, which may display blue dots up to one inch in diameter as part of their rear stop lamps, turn indicators, hazard lamps, or reflectors.

Using blue lights during the commission of a felony triggers a separate, harsher penalty under O.C.G.A. 40-8-90(c): a fine of not less than $1,000, imprisonment of not less than one year, or both. Those are floors, not caps.¹

Red Lights Require an Emergency Vehicle Permit

Red flashing or revolving lights are reserved for designated emergency vehicles. Under O.C.G.A. 40-8-92, the Commissioner of Public Safety designates an emergency vehicle by issuing a permit. The permit is valid for five years and costs $2.00. Government agencies and licensed ambulance providers pay nothing. Applicants must show a proven need before a permit is issued.²

Some vehicle categories skip the permit requirement entirely:

Marked law enforcement vehicles, for blue lights, if they meet the marking rules in O.C.G.A. 40-8-91.
Marked fire department vehicles, for red lights, if distinctly marked on each side.
Licensed ambulances, for red lights.
Low-speed vehicles, for amber strobes.

Amber Lights for Tow Trucks and Road Service

Amber has its own statute. O.C.G.A. 40-8-35 requires tow trucks, wreckers, and emergency road service vehicles to run flashing or revolving amber lights in three situations: at the scene of an accident or breakdown, while towing a vehicle in a way that leaves any wheel of the towed vehicle on the pavement, and when carrying protruding objects that create a hazard.³

The amber equipment must be visible under normal conditions from 500 feet, from both front and rear. Tow and road service operators do not need a separate permit under this section to run amber lights.

Green Lights Are Not Allowed on Private Vehicles

Georgia does not authorize green lights on volunteer firefighter vehicles or any other private vehicle. O.C.G.A. 40-8-92(d) makes it unlawful to operate or park any vehicle on public property with flashing or revolving green lights. The single exception covers vehicles used by law enforcement, fire departments, emergency management agencies, or other government entities to mark a command post at an emergency scene.²

Georgia differs from several states that permit green courtesy lights for volunteer responders. Check with your department before installing anything.

Underglow and Accent Lighting

Georgia does not specifically ban underbody or accent lights. You can install them, but the color and behavior are constrained by the same statutes that govern other aftermarket lighting. Any underglow that flashes, blinks, oscillates, or revolves runs into the restrictions on non-emergency flashing lights, and any blue, red, or green underglow runs directly into O.C.G.A. 40-8-90 and 40-8-92.¹

Practically, amber and white steady lights are the safest choices. Purple carries some risk because a red-and-blue combination can be read as an emergency-vehicle color pattern, and mimicking an emergency vehicle brings steeper consequences than a plain equipment violation.

Headlight Color

Georgia requires vehicle lighting to conform to SAE J578 color standards. For headlights, the output must fall within the range classified as white. Standard halogen bulbs and most factory HID and LED headlights meet this. Aftermarket HID and LED bulbs generally comply if the color temperature stays roughly between 5,000K and 6,000K.

Problems appear at the extremes. Bulbs above roughly 6,000K start shifting toward blue, which risks failing SAE’s white classification and edges toward the blue-light prohibition in O.C.G.A. 40-8-90. Colored covers or tinted lenses that alter the output color create the same problem.

Brake Lights and Turn Signals Are Exempt

O.C.G.A. 40-8-93 makes clear that the restrictions in 40-8-90 and 40-8-92 do not apply to blinking or flashing parking lights, brake lights, or directional turn signals. Factory red and amber flashing behavior on those specific lights is not a violation, even though they are colored and they flash.⁴

Buying a Former Patrol Car

O.C.G.A. 40-8-91 makes it a separate misdemeanor offense to paint, mark, or equip any vehicle to look like a law enforcement vehicle. Georgia State Patrol vehicles follow specific two-tone paint schemes, carry blue lights visible from 500 feet, and display “State Patrol” in letters at least six inches tall. Other law enforcement vehicles must be marked on each side and the back with the agency name in letters at least four inches tall.⁵

When a law enforcement vehicle is retired or sold, the agency must remove all lettering and colored lights. If you buy a decommissioned patrol car at auction, verify the lights and decals have been stripped before driving it on public roads. Driving one that still has its markings and emergency lights is a misdemeanor.⁵

Parade Exception

O.C.G.A. 40-6-7 lets the local authority that issues a parade permit authorize otherwise non-compliant vehicles, including those with flashing lights or sirens, to participate, provided the authority determines the vehicles will not endanger anyone. The exception applies only during the authorized event. Installing restricted lights for a parade and then driving on public roads afterward still violates the colored-light statutes.⁶

Penalties

Most colored-light violations are misdemeanors. O.C.G.A. 40-8-96 states that any person violating 40-8-90 or 40-8-92 is guilty of a misdemeanor.⁷ Under O.C.G.A. 17-10-3, a misdemeanor can bring a fine of up to $1,000, jail time of up to 12 months, or both. First-time offenders on lighting alone are more likely to receive a fine or a citation to bring the vehicle into compliance than jail time.⁸

The heavy scenario is using blue lights while committing a felony under O.C.G.A. 40-8-90(c): a mandatory minimum $1,000 fine, a minimum one year in prison, or both, with no ceiling on how much longer a judge can go.¹

Federal Certification Still Applies

Beyond Georgia’s rules, every vehicle on U.S. roads must comply with Federal Motor Vehicle Safety Standard No. 108, at 49 CFR 571.108. FMVSS 108 sets baseline requirements for headlamps, tail lamps, turn signals, reflectors, and associated equipment. Compliant products carry a DOT or SAE marking physically molded or printed on the lens or housing.⁹

A housing without that marking has not been certified. Even if the color and behavior comply with Georgia law, missing federal certification can independently make the light illegal. This shows up often with cheap imported LED bars and accent housings sold online. No marking, treat it as non-compliant, regardless of what the listing says.
