Texas Neon Underglow Laws

Personalizing your vehicle with neon underglow lights can be a striking way to express your unique style and make your car stand out. However, it’s crucial to be aware of the specific regulations governing neon underglow lights in Texas. Understanding the laws is not only essential to avoid legal troubles but also to ensure your safety and the safety of other road users. In this blog post, we’ll explore Texas neon underglow laws, what’s permitted, what’s not, and how to use them responsibly.

Is neon underglow legal in Texas?

Under Texas law, there are no specific restrictions on additional aftermarket vehicle lighting, including neon underglow. As such, our conclusion is that neon underglow is generally considered legal in Texas, with the following conditions:

  1. Prohibition of flashing, rotating, or oscillating lights on civilian vehicles, except for emergency lamps under specific circumstances (as outlined in Sec. 547.331) during traffic hazards.
  2. No red lights should be visible from the front of the vehicle.
  3. Although not explicitly prohibited unless flashing, we strongly recommend avoiding the use of red and blue colors, or any combination of red, blue, and white on aftermarket car lighting.
  4. Texas laws explicitly permit underglow on motorcycles, but they should be non-flashing and limited to white and amber lights. For cars, Texas also allows fender lights and running board courtesy lamps.
  5. There are no specific Texas laws that prohibit the installation of underbody lighting, making it generally legal for use while driving.
