Is neon underglow legal in New Mexico?

New Mexico law does not restrict using additional vehicle lighting which would include neon underglow. Therefore it’s our conclusion that in New Mexico neon underglow is not illegal, according to the following restrictions:

  • No red light may be visible from the front of the vehicle
  • No flashing lights are permitted

Furthermore we recommend avoiding colors green, red and blue on any aftermarket lights installed on your car, due to these colors typically being reserved for use on emergency vehicles.

There are no relevant NM laws which specifically restrict or prohibit installing underbody lighting, meaning we consider it legal to use it while driving.
