Usage of neon underglow lighting is governed by New Jersey Revised Statutes, Title 39: Motor Vehicles and Traffic Regulation, Sections 39:3-46 to 39:3-66-3.
Is neon underglow legal in New Jersey?
New Jersey law does not restrict using aftermarket 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 New Jersey neon underglow is not illegal.
Since it’s not specifically forbidden, underbody lights could be considered legal assuming the following:
- all lights visible from the front of the car must be white or amber
- all lights visible from the front sides of the car must be amber
- all lights visible from the back or near back of the car must be red
- license plate illumination must be white
- no flashing lights may be used
No other colors of lights are permitted on vehicles!
There are no relevant laws to restrict or prohibit installing neon car underglow, meaning it’s not illegal to use it while not on a public road. Ensure your neon lights are unable to change color to restricted colors.
