Texas Underglow Laws 

Underglow lighting is a popular way to give your vehicle a unique look by adding lights to the underside. No doubt you’ve seen these customized vehicles cruising down the freeway. However, the modern LED setups can do a lot more than just glow. They can change colors, create “chase” effects, or even pulse to the beat of your favorite songs. While underglow itself isn’t illegal in Texas, there are rules in place to keep everyone safe. Lights that flash, rotate, strobe, or oscillate can distract other drivers and are not allowed. 

Texas Vehicle Lighting Laws 

The following rules apply to all standard vehicles on Texas roads and help make sure that everyone can see and be seen while driving. Here’s a quick overview: 

1. Front turn signals must be either white or amber. 
2. Certain colors, such as red, white, and blue, are reserved for emergency vehicles only. 
3. Vehicles are required to have at least two red taillights visible from the rear.
4. Brake lights must be bright enough to be seen from a reasonable distance in normal conditions. 
5. Headlights must be properly aligned and in working order to avoid blinding other drivers. 
6. License plate lights must illuminate the plate so it is clearly readable at night. 
7. Reflectors and marker lights must be in place and functional as required by vehicle type. 
8. No flashing, strobe, or rotating lights are allowed unless you are an authorized emergency vehicle. 

Legal Underglow Colors In Texas: 

• White 
• Amber 

Illegal Underglow Colors: 

While there aren’t laws specifically banning the following colors, you run the risk of getting pulled over and getting ticketed for anything other than the standard white and amber lights. 

• Red (front or side) 
• Blue (front or side) 
• Green 
• Purple
• Multi-color or flashing/strobing lights that are distracting 
• Any other color visible from the front or sides that could be confused with emergency vehicle lights 

Are Rock Lights Legal in Texas? 

Rock lights are a type of LED lighting installed on the underside of off-road vehicles, usually near the wheel wells and suspension. Unlike typical underglow that’s mainly for looks, rock lights are designed to illuminate the ground around your tires, making it easier to see rocks, ruts, and obstacles when you’re off-roading at night. 

Think of it this way: underglow is like putting your car in a spotlight for everyone to admire, while rock lights are more like carrying a flashlight for your wheels. They’re practical for safety and navigation off-road, but they can still add a bit of style if you want. Some rock lights even have color options, but unlike flashy underglow meant for show, their main purpose is functional visibility. 

While Texas law doesn’t mention rock lights specifically, they fall under the same category as auxiliary or aftermarket lighting. The rules are as follows: 

1. Stick with using white or amber lights 
2. No rotating, flashing, or oscillating lighting 
3. No red or blue lights allowed

Are Smoke Tail Lights Legal In Texas? 

Smoked lights are basically a modification that tints your lamps to give a cool and unique look. Unfortunately, this process reduces the brightness of taillights, making them illegal and less safe on the road. The law requires that tail lights remain red and clearly visible from at least 1,000 feet away in normal lighting conditions. This means you can darken or tint your lights, but they can’t be so dark that other drivers have trouble seeing your brake or turn signals. You’re taking a big risk by reducing the brightness of your taillights in any way. 

When and Where the Lamps Can Be Used 

You can add extra driving lights to your vehicle, but you’re limited to just two. Driving lamps are meant to provide extra visibility in low-light or poor weather conditions, such as at night, in fog, or on rural roads with limited street lighting. They need to sit between about 16 and 42 inches off the ground and must be aimed so they don’t blind other drivers. Once again, only white or amber bulbs are allowed, and flashing or strobe effects aren’t legal. Beyond these, other aftermarket lighting like underglow, light bars, or rock lights can be used as long as they follow the state’s rules on brightness, color, and placement. 

Are They Legal On Motorcycles? 

Yes, underglow lights are allowed on motorcycles, but there are some specifics to keep in mind. Only white or amber lights can be used on a motorcycle or moped since red and blue are reserved for emergency vehicles. It’s also important to make sure the lights are positioned so they aren’t a distraction to other drivers. 

Penalties For Violations 

If your vehicle lighting doesn’t comply with the law, you can certainly face penalties. Violating these rules can result in a Class C misdemeanor, with a fine of up to $500. You will also most likely be required to remove the non-compliant lights from your vehicle. 

Tips for Keeping Your Vehicle Lighting Street-Legal in Texas 

Even if your lights are allowed, how you use and maintain them really matters. It’s a good idea to check that all your bulbs are working and the lenses are clean. Dirt or foggy covers can make your lights less visible and less effective. When adding aftermarket lights, check that they don’t stick out too far or block any required lights on your vehicle. 

It’s also important to secure your wiring and mounting. Loose connections or poorly installed lights can flicker, short out, or even fall off while you’re driving. If you upgrade to brighter or specialty bulbs, make sure they meet Texas brightness limits and are aimed properly so they don’t shine into oncoming traffic. Keep in mind that some cities may have stricter rules than the state, so it’s worthwhile to check local regulations.
