Minnesota Neon Underglow Laws

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

Minnesota laws for neon underglow are found in Minnesota Statutes, Transportation, Chapter 169, Section 169.64: Prohibited Lights.

Is neon underglow legal in Minnesota?

Minnesota law specifically prohibits additional (aftermarket) vehicle lighting. Neon underglow is considered an aftermarket vehicle modification and is therefore not legal. In short, in Minnesota neon underglow is illegal.

Furthermore there are following following restrictions on vehicle lighting:

  • The only color which may be visible from the front of the vehicle is white or amber, and the only permissible color visible from the back of the vehicle is red or amber.
  • Blue and red lights are explicitly prohibited for civilian vehicles, and you may not use any kind of flashing lights. All colors except those permitted for required vehicle lights (white, amber, red) are prohibited for use.

Here’s an excerpt from the pertinent section of MN laws:

Unless otherwise authorized by the commissioner of public safety, no vehicle shall be equipped, nor shall any person drive or move any vehicle or equipment upon any highway with any lamp or device displaying a red light or any colored light other than those required or permitted in this chapter.

Since this excerpt is a bit ambiguous, one could argue it only refers to using colors other than white, amber or red. In that case this would technically mean you could install neon underglow in Minessota if the colors were either white, amber, or red.

Unfortunately, because of the law’s ambiguity we strongly suggest not using car underglow in Minessota while driving. Even the installation of lighting equipment not specifically required or permitted is technically illegal in MN. If you wish to install it for use on private property, do so at your own risk.
