Is Underglow Legal in Georgia? (2026 Guide)

Two rules are nearly universal across the US: no red light shown to the front and no blue underglow (both are reserved for emergency vehicles), and no flashing, rotating, or strobing lights while driving. Beyond that, states differ. Here is how Georgia handles it.

Underglow rules in Georgia

• Colors: Blue is prohibited by statute, any device capable of producing blue light is barred on non-authorized vehicles. Red is reserved for emergency vehicles. Green flashing or revolving lights are prohibited for private persons. To be safe, avoid red, blue, and green.
• Capability counts: Because an RGB kit can produce a banned color, a kit capable of blue can be treated as a violation even if you never switch to it. Choose your settings carefully.
• No flashing: Flashing, blinking, and revolving lights are prohibited except for permitted and government vehicles.
• Driving vs parked: Permitted while driving if it is steady and in an allowed color.

Underglow while parked or on private property

These laws generally govern vehicles on a public road or highway, so on genuinely private property, a private parking lot, driveway, car show, or off-road, underglow use is usually far less restricted. It is not a blanket "legal when parked" rule, though. A car parked on a public street is usually still treated as being on the highway, so the color limits (no red or blue to the front) and equipment rules still apply. Red or blue lighting can also trigger separate police-impersonation laws based simply on having or using it, whether or not the car is moving. When in doubt, keep to compliant colors and check your local ordinances.

Georgia also prohibits a device that is merely capable of producing blue light, so an RGB kit that can turn blue can be an issue even when it is parked or switched off. Keep your kit set to clearly permitted colors.

How to stay legal with underglow in Georgia

• Keep the lights steady-burning, never flashing, strobing, or rotating.
• Show no red light to the front, and avoid blue entirely.
• Do not mimic emergency-vehicle lighting or obscure your license plate.
• Confirm the current rule below and check locally before driving with it on.

The law

OCGA section 40-8-90 (blue lights) is the clearest prohibition; sections 40-8-91 and 40-8-92 cover emergency designations and the ban on flashing or revolving green by private persons. Confirmed via FindLaw and Justia. You can read the referenced law here: Georgia statute.

Georgia Underglow FAQ

Is blue underglow legal in Georgia?
No. Georgia statute prohibits any device capable of producing blue light on non-authorized vehicles, so blue underglow is not allowed.

What underglow colors are safe in Georgia?
Avoid red, blue, and green. Since an RGB kit can produce a banned color, be careful with your color settings, keeping to clearly permitted colors and steady operation.

Can I have underglow on while parked in a lot?
On genuinely private property, such as a private lot, driveway, or car show, underglow use is generally far less restricted. On a public street a parked car is usually still treated as being on the highway, so the color rules still apply, avoid red and blue, and check your local ordinances.
