Maine Neon Underglow Laws

Maine neon underglow usage is governed by the state's Code. All relevant laws, rules and regulations pertaining to vehicle lighting including car underglow in Maine 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 Maine Revised Statutes, Title 29: Motor Vehicles and Traffic, Chapter 17: Equipment, Subchapter 1: General Provisions.

Is neon underglow legal in Maine?

Neon underglow is illegal in Maine, and the law concerning it is very specific and restrictive.

Based on the following excerpt from Maine laws, you are not allowed to display neon underglow on public streets or while driving:

[…] A vehicle may be equipped with under-vehicle lighting for the purpose of participating in shows, events or other exhibitions, but the lighting may not be used or the vehicle illuminated with under-vehicle lighting on a public way.

Car underglow can legally be used for shows or exhibitions, but make sure you never use it while driving. Additionally we don’t recommend using it on public parking lots either, as an over-eager police officer may still be able to give you a citation.

Furthermore such underbody lights may only display white or amber on the front, amber on the side, and amber or red in the rear of the car. Lights may not rotate or flash in any way.

As defined by law auxiliary lights are in fact additional headlamps and fog lights; Maine however puts undercarriage lights within the same category which may restrict colors to the above. In case you never intend to use car underglow in public you may be able to use any color, but use at your own risk.
