Is neon underglow legal in Rhode Island?

Rhode Island law does not restrict additional vehicle lighting which would include neon underglow. Therefore it’s our conclusion that in Rhode Island neon underglow is not illegal, but ensure you avoid the following restrictions:

  • License plate illumination must be white
  • Red lights in front of the car are expressly prohibited
  • Flashing lights are not permitted (except for authorized vehicles, or for signalling a traffic hazard or turn)

We strongly recommend avoiding colors blue and red on all aftermarket lights installed on your car as these are used by police vehicles.

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