Usage of neon underglow lighting is governed by Alabama Revised Statutes, Title 32: Motor Vehicles and Traffic, Chapter 1: General Provisions, Article 9: Equipment, Division 2: Lights, Lamps and Reflective Devices.
Is neon underglow legal in Alabama?
Alabama law does not specifically restrict additional aftermarket vehicle lighting which would include neon underglow. Therefore it’s our conclusion that in Alabama neon underglow is not illegal, as long as you follow these restrictions:
- No red lights may be visible from the front of the vehicle
- License plate illumination must be white
- Flashing lights are prohibited
We highly recommend avoiding blue and red colors on any aftermarket lights including underbody glow, as these colors are typically used for emergency vehicles. To be safe you should only use white or amber underglow.
There are no relevant AL laws which specifically allow or prohibit installing car underglow, meaning we consider it legal to use it while driving.
