Utah Neon Underglow Laws

Utah neon underglow usage is governed by the state's Code. All relevant laws, rules and regulations pertaining to vehicle lighting including car underglow in Utah have been provided below. Make sure to examine the regulations carefully and do not use any restricted lights.

Usage of neon underglow lighting is governed by Utah Code, Title 41: Motor Vehicles, Chapter 6a: Traffic Code, Part 16: Vehicle Equipment.

Is neon underglow legal in Utah?

Utah law does not restrict additional aftermarket vehicle lighting which would include neon underglow. Therefore it’s our conclusion that in Utah neon underglow is not illegal, as long as you adhere to the following restrictions:

  • No red or blue lights may be visible from the front of the car
  • No flashing or rotating lights are allowed

To be safe we recommend avoiding red and blue colors altogether, and any combination of red, blue and white lights which may imitate an emergency vehicle.

There are no relevant UT laws to restrict or prohibit installing underbody lighting, thus we consider it legal to use while driving.

Note: we’ve been advised by a member of Utah Highway Patrol that unless the vehicle is on private property, off-road or being used for display purposes only, all underglow is illegal. We are unable to find any laws or statutes to support this claim. Use at your own risk.
