Indiana Neon Underglow Laws

Indiana neon underglow usage is governed by the state's Code. All relevant laws, rules and regulations pertaining to vehicle lighting including car underglow in Indiana 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 Indiana Code, Title 9: Motor Vehicles, Article 19: Motor Vehicle Equipment, Chapter 6: Lights, Reflectors, an Turn Signals.

Is neon underglow legal in Indiana?

Indiana law does not restrict additional aftermarket vehicle lighting which would include neon underglow. Therefore it’s our conclusion that in Indiana neon underglow is not illegal, as long as you follow these restrictions:

  • License plate illumination must be white
  • Flashing lights are prohibited
  • All combinations of red, blue, white, and amber colors are illegal

Though there are no specific restrictions that say otherwise, to stay completely within regulations in Indiana laws consider using lights on the front of the vehicle which are amber. License plate illumination must be white, while other illumination on the rear or a vehicle should be red.

Flashing lights on civilian vehicles are only permitted for warning other drivers about potential hazards, with white and amber being the only legally allowed colors in this case. You should never display flashing or revolving red, blue, or green lights, as they are reserved for emergency vehicles (fire department, ambulance, police cars, etc.).

We recommend avoiding red, blue and green colors altogether. Any combination of these colors with white or amber is also illegal to use.

There are no relevant IN laws which specifically restrict or prohibit installing car underglow, meaning we consider it legal to use it while driving.
