Yes, you can use certain neon lights, often called "underglow" lighting, on your car in Nevada, but the law places significant restrictions on their color and when they can be illuminated. The key rule is that while driving on public roads, you cannot use red, blue, or flashing lights, as these are reserved for emergency and law enforcement vehicles. Other colors like white, amber, or purple are generally permissible only when the vehicle is parked, not in motion.
The regulations are outlined in the Nevada Revised Statutes (NRS) Chapter 484. Specifically, NRS 484D.230 governs the use of auxiliary lights. The law is designed to prevent confusion with official emergency vehicles. Using prohibited colors or having the lights on while driving can result in a traffic citation and a fine.
Key Nevada Restrictions on Neon Car Lights:
| Regulation Aspect | Specific Rule | Rationale |
|---|---|---|
| Permissible Colors (while parked) | Most colors except red and blue are allowed. | To avoid impersonating emergency vehicles. |
| Prohibited Colors (while driving) | Red, blue, and flashing lights are strictly illegal. | Reserved for police, fire, and ambulances. |
| Light Placement | Lights cannot be mounted in a way that interferes with required lights (e.g., brake lights). | Ensures vehicle safety signals remain clear. |
| Legal Status When Parked | Non-red/blue underglow can be used off-public roadway or when legally parked. | Considered for show purposes, not for active driving. |
| Potential Penalty | A moving violation ticket and fine. | Enforcement is strict due to public safety concerns. |
If you're installing underglow for car shows or off-road use, it's a popular modification. However, for daily driving, the practical use is very limited. The safest approach is to install a switch that allows you to easily turn the underglow system off completely when you're on public streets to avoid any potential legal issues. Always prioritize not distracting other drivers or mimicking emergency services.

As someone who got a ticket for this in Reno, I can tell you it's not worth the hassle. My blue underglow looked cool parked, but I forgot to turn it off driving home. Cop pulled me over immediately. He said it's a straight-up safety issue—they can't have people confusing my Civic with a police car. Now I only turn them on when I'm parked at a meet. Stick to white or amber if you must, but even then, keep it for show, not for the road.
