Missouri Neon Underglow Laws

Neon underglow lights have long been a popular way for car enthusiasts to add a unique and eye-catching element to their vehicles. These vibrant lights can create a distinctive look and set a car apart from the rest. However, if you’re in Missouri and considering adding neon underglow to your vehicle, it’s important to understand the state’s laws and regulations regarding this aftermarket lighting.

Is neon underglow legal in Missouri?

Missouri law allows for additional vehicle lighting, including neon underglow, without specific restrictions. However, there are certain guidelines to follow:

  1. No red color should be visible from the front of the vehicle.
  2. Flashing neon lights are not permitted.
  3. License plate illumination must be in white.

Furthermore, it is advisable to avoid using red and blue colors on any aftermarket lights on your car, including underbody glow. While the State of Missouri does not explicitly prohibit the use of blue color, it’s recommended to avoid it because many states restrict blue lighting as it can be mistaken for a police or emergency vehicle.

In summary, there are no specific Missouri laws that prohibit or restrict the installation of neon car underglow, making it generally legal to use while driving in the state.
