Usage of neon underglow lighting is governed by Mississippi Statutes, Title 63: Motor Vehicles and Traffic Regulations, Chapter 7: Equipment and Identification, General Provisions.
Is neon underglow legal in Mississippi?
Mississippi law does not restrict additional after-market vehicle lighting which would include neon underglow, but it does restrict colors which may be visible while the car is in motion. Therefore it’s our conclusion that in Mississippi neon underglow is not illegal.
Since it’s not specifically forbidden we consider neon car underglow legal assuming the following restrictions:
- all lights visible from the front of the car must be white or amber
- all lights visible from the side of the car must be amber
- all lights visible from the back of the car must be red
- license plate illumination must be white
- no flashing lights may be used
There are no relevant MS state laws to restrict or prohibit installing underbody lights, meaning they are legal to use while not on a public road.
