Is Underglow Legal in Arkansas? (2026 Guide)

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

Underglow rules in Arkansas

• Not road-legal: Summaries of Arkansas law indicate that using non-original exterior lighting while driving on a public road is unlawful, so underglow use is effectively limited to private property and off-road.
• Colors: No red, blue, or green light visible from directly in front. Flashing is prohibited except for statutory exceptions.
• Brightness: A lamp over 300 candlepower must not strike the road beyond 75 feet.

Underglow while parked or on private property

Because Arkansas does not permit lit underglow on public roads, genuinely private property, a private lot, driveway, car show, or off-road, is the practical place to enjoy it, and those road rules generally do not reach private property. Be aware that a car parked on a public street is usually still treated as being on the highway, and red or blue lighting can trigger separate police-impersonation laws regardless of motion. Keep to compliant colors and check local ordinances.

How to stay legal with underglow in Arkansas

• 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.

Arkansas Underglow FAQ

Is underglow legal in Arkansas?
Underglow is not permitted for use while driving on public roads; installation and private-property use are the workaround. Keep the lights steady, show no red to the front, and avoid blue.

What underglow colors are illegal in Arkansas?
No red, blue, or green visible from directly in front; and non-original exterior lighting is restricted on the road. Flashing or strobing of any color is not allowed.

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.
