For those of you who are wondering “are grill glow lights legal in Texas?”

The short answer is yes, but it’s not without a few restrictions.

Texas laws don’t prohibit the use of aftermarket or non-mandatory lights on vehicles, so something like grill glow lights would be considered legal. However, flashing, oscillating and other non-stationary lights would be considered illegal due to the distraction they may cause on the road.

Before you consider installing those blue LED grill lights on your ride, you need to note that you could stand a chance of being charged with impersonating an emergency vehicle. To avoid any unnecessary hassle, make sure to stay clear of any red or blue glow, flashing, stationary or otherwise!

Extra Information


I found this in the sticky that I have posted within this section.

(a) A motor vehicle lamp or illuminating device, other than a headlamp, spotlamp, auxiliary lamp, turn signal lamp, or emergency vehicle, tow truck, or school bus warning lamp, that projects a beam with an intensity brighter than 300 candlepower shall be directed so that no part of the high-intensity portion of the beam strikes the roadway at a distance of more than 75 feet from the vehicle.

(b) Except as expressly authorized by law, a person may not operate or move equipment or a vehicle, other than a police vehicle, with a lamp or device that displays a red light visible from directly in front of the center of the equipment or vehicle.

(c) A person may not operate a motor vehicle equipped with a red, white, or blue beacon, flashing, or alternating light unless the equipment is:(1) used as specifically authorized by this chapter; or

(2) a running lamp, headlamp, taillamp, backup lamp, or turn signal lamp that is used as authorized by law.(d) A vehicle may be equipped with alternately flashing lighting equipment described by Section 547.701 or 547.702 only if the vehicle is:

Acts 1995, 74th Leg., ch. 165, Sec. 1, eff. Sept. 1, 1995. Amended by Acts 1999, 76th Leg., ch. 380, Sec. 1, eff. July 1, 1999.Amended by: Acts 2011, 82nd Leg., R.S., Ch. 229, Sec. 3, eff. September 1, 2011.

I read it as you cannot have a blue beacon, or flashing light. It does not really say anything about having a solid on blue light. I would just either call or go talk to someone at the police department about it before running on the truck. Just to be on the safe side. You might get told no and it still be fine.

It just depends on the police that tell you the info. Most of them actually do not know the laws about lighting.


From the code itself:
32-5-241. Auxiliary lamps
d) Special restriction on lamps.

Any lighted lamp or illuminated device upon a motor vehicle other than head lamps, spot lamps, auxiliary lamps or flashing front direction signals which projects a beam of light of an intensity greater than 300 candlepower shall be so directed that no part of the beam will strike the level of the roadway on which the vehicle stands at a distance of more than 75 feet from the vehicle.

No person shall drive or move any vehicle or equipment upon any highway with any lamp or device thereon displaying a red light visible from directly in front of the center thereof. This section shall not apply to authorized emergency vehicles.

Any vehicle may be equipped with flashing lamps which may be used for the purpose of warning the operators of other vehicles of the presence of a vehicular traffic hazard requiring the exercise of unusual care in approaching, overtaking or passing, and when so equipped may display such warning in addition to any other warning signals required by this section. The lamps used to display such warning to the front shall be mounted at the same level and as widely spaced laterally as practicable and shall display simultaneously flashing white or amber lights, or any shade of color between white and amber. The lamps used to display such warning to the rear shall be mounted at the same level and as widely spaced laterally as practicable, and shall show simultaneously flashing amber or red lights, or any shade of color between amber and red. These warning lights shall be visible from a distance of not less than 1,500 feet under normal atmospheric conditions at night.

Flashing lights may be used on motor vehicles as a means of indicating a right or left turn; a stop lamp may pulsate with different intensities provided that it meets at all intensities the provisions of subdivision (2) of subsection (b) of this section; and the warning lights on emergency vehicles may flash.
