Is neon under-glow legal in Nevada?
Updated: Jun 11, 2021
Nevada law does not specify nor restrict additional vehicle lighting equipment which would include neon under-glow. Therefore it’s concluded that in Nevada neon under-glow is not illegal, as long as you adhere to the following restrictions:
No amber flashing lights are permitted
All aftermarket lights visible from the rear of the car should be red
License plate illumination must be white
It is highly recommend avoiding blue and red colors on all aftermarket lights including underbody glow, as these colors are typically used on emergency vehicles.
Although not specifically required, to stay completely within the law you may want to consider using amber colored car under-glow in front and front sides of a vehicle, and red glow in the back and back sides.
There are no relevant NV laws which specifically restrict or prohibit installing car under-glow, meaning it's consider legal to use it while driving.
