Is Underglow Legal in Mississippi? (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 Mississippi handles it.

Underglow rules in Mississippi

• Colors: While in motion, the front must be white or amber, sides amber, and rear red. Blue lights are unlawful for non-emergency vehicles, and red is restricted.
• No flashing: Flashing, blinking, or strobe effects are prohibited on public roads.
• Driving vs parked: The color rules apply while in motion or in use on public roads; off public roads, installation and use are not restricted by these provisions.

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 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) still apply, and red or blue lighting can trigger separate police-impersonation laws regardless of whether the car is moving. Keep to compliant colors and check your local ordinances.

How to stay legal with underglow in Mississippi

• 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.
