Are Rock Lights Legal in Texas? (And Wheel Lights Too)
Short answer: steady pure white or amber accent lighting is generally allowed on Texas roads, while flashing, strobing, or emergency colors are not. This is general guidance, not legal advice.
- Generally allowed: steady, true pure white or amber accent lighting.
- Not allowed: flashing, strobing, or chasing patterns while you drive on public roads.
- Not allowed: red or blue light shown toward the front, since that reads as an emergency vehicle.
- Not allowed: glare bright enough to blind or distract oncoming drivers.
- Always: keep your license plate and every required lamp fully visible.
Short answer: steady-burning pure white or amber accent lighting is generally not specifically prohibited on Texas roads, but flashing, strobing, or red and blue lighting is a different story. Here is what the law actually says, in plain language.
What Texas law actually restricts
The relevant statute is Texas Transportation Code § 547.305. It does not mention rock lights, wheel lights, or underbody lighting by name. What it restricts is specific colors and behaviors:
- No red visible from directly in front. A motor vehicle may not carry a lamp that shows red light visible from directly in front of its center.
- No flashing, rotating, or alternating red, white, or blue. Those signal emergency vehicles, and running them on a civilian truck is treated seriously.
- No unreasonable glare. Lighting cannot blind or dazzle other drivers.
What that means for rock lights
Steady-burning pure white rock lights under the truck do not, by themselves, fall under any of those specific prohibitions. The practical risks come from configuration: running a strobe or chase pattern on public roads, pointing output where it glares at oncoming traffic, or running colors that read as emergency lighting. Some manufacturers of RGB kits label them off-road-only for exactly this reason.
What that means for wheel lights
The same principles apply. Steady white or amber wheel lighting is not named in the statute; flashing or emergency-colored displays are where trouble starts. Amber is the most conservative accent color on the road, it is the color the law already expects on signals and markers.
The caveats
- Sources genuinely disagree. Some lighting manufacturers state that accent lighting is not street-legal at all as a blanket position; others say steady white or amber is fine in most states. Both camps are simplifying, statutes differ state by state and are enforced with officer discretion.
- Cities and counties can layer their own rules on top of state law.
- Outside Texas, check your state. The pattern, steady white/amber usually tolerated, flashing and red/blue prohibited, repeats widely, but the details vary.

Where Southern Lumen lands on this
Our flagship lights are steady, true pure white, the most conservative choice you can make short of leaving the lights off. Our switchback kits use white and amber, the two colors road law is most comfortable with. If you want a setup you can run without second-guessing every patrol car, that is the practical reason to skip the color-cycling kits.

Frequently asked questions
Are rock lights illegal in Texas?
No, not by themselves. Texas law does not name rock lights, and steady pure white or amber accent lighting is generally allowed. Trouble starts with flashing, strobing, or emergency colors like red and blue shown to the front.
Is it illegal to have rock lights on your truck?
Having them installed is not the problem. What matters is how you run them on public roads. Keep them steady and pure white or amber, keep your plate and required lamps visible, and you are on the conservative side of the law.
Can you drive with rock lights on?
In general, yes, as long as they burn steady and stay pure white or amber. Turn off any flashing, strobing, or color-cycling pattern before you hit the road. Do not aim them where they glare at oncoming traffic.
Are wheel lights legal in Texas?
The same rules apply as rock lights. Steady white or amber wheel lighting is generally allowed, while flashing or emergency-colored displays are where you get into trouble. Amber is the most conservative accent color on the road.
