Texas Neon Underglow Laws

Texas neon underglow usage is governed by the state's Code. All relevant laws, rules and regulations pertaining to vehicle lighting including car underglow in Texas 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 Texas Transportation Code, Title 7: Vehicles and Traffic, Subtitle C: Rules of the Road, Chapter 547: Vehicle Equipment.

Is neon underglow legal in Texas?

Texas law does not restrict additional aftermarket vehicle lighting which would include neon underglow. Therefore it’s our conclusion that in Texas neon underglow is not illegal, assuming you adhere to the following restrictions:

  • No flashing, rotating or oscillating lights are permitted on civilian vehicles (only exception is in Sec. 547.331. allowing emergency lamps in case of traffic hazards)
  • No red lights may be visible from the front of the vehicle

Although not expressly prohibited unless flashing, we strongly suggest avoiding colors red and blue, or a combination of red, blue and white on any after-market car lighting.

Texas laws also explicitly permits underglow on motorcycles, but only non-flashing white and amber lights are allowed. On cars Texas also allows fender lights, and running board courtesy lamps.

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

This chapter does not prohibit and the department by rule may not prohibit the use of:

(1) equipment required by an agency of the United States; or

(2) a part or accessory not inconsistent with this chapter or a rule adopted under this chapter.

This provision is important to note since it essentially permits using aftermarket vehicle lighting as long as it’s not in violation of other regulations.

A motor vehicle may be equipped with:

(1) not more than two side cowl or fender lamps that emit an amber or white light without glare;

Penalties

As per Section 547.004 – General Offenses, driving a vehicle not in compliance with the lighting regulations is considered a misdemeanor.

Sec. 547.004. GENERAL OFFENSES.

(1) is unsafe so as to endanger a person;

(2) is not equipped in a manner that complies with the vehicle equipment standards and requirements established by this chapter; or

(3) is equipped in a manner prohibited by this chapter.
