Having blue lights on your license plate might seem cool, but it can land you in serious legal trouble. Police may pull you over, issue a fine, or even impound your vehicle. Thankfully, understanding state regulations on colored lights helps you avoid unnecessary stops.
Most U.S. states prohibit blue lights on civilian vehicles because they’re reserved for emergency responders, making them a potential safety and legal issue.
Even decorative lights can be illegal—keep reading to avoid legal trouble.
Consult your state laws and remove unauthorized blue lights to stay safe and legal.
Are blue lights on license plates illegal?
Yes, in most U.S. states, blue lights are restricted to emergency vehicles such as police cars, ambulances, and fire trucks. Civilian use can result in a traffic stop and penalties. For example, in California, Vehicle Code Section 25258 explicitly forbids blue lights on non-emergency vehicles unless authorized by law.
Some car enthusiasts install blue LEDs around their license plate as an aesthetic choice, unaware of the legal implications. Law enforcement officers may interpret this as impersonation of a police vehicle or a distraction to other drivers.
Even if your lights are dim or only partially visible, they may still be considered illegal. This applies both to the front and rear license plates and includes lights embedded in plate frames or covers.
Why are blue lights regulated?
Blue is universally recognized as an emergency vehicle color in the U.S. When civilians use it, it can confuse other drivers and slow down the response of actual emergency vehicles. Police often monitor for this issue, especially during nighttime driving when lights are more noticeable.
Unauthorized lighting may also violate regulations about modifying your vehicle beyond road-safe standards. Blue lights tend to stand out in low-light environments, potentially distracting or alarming other motorists, which increases the risk of accidents.
State-by-state variations
While most states follow a similar rule, there are nuances. For example:
- Texas: Blue lights on vehicles not part of emergency services are illegal.
- Florida: Only authorized emergency vehicles can display blue lights.
- New York: License plate lighting must be white only.
Some states may also allow certain colored lights during parades or with special permits—but not for everyday road use.
Before installing any colored lighting, it’s wise to research local motor vehicle codes or contact your DMV.
What happens if I get caught?
Penalties vary by location. Common consequences include:
- Traffic tickets
- Fix-it citations requiring removal of the lights
- Vehicle impoundment in severe cases
- Points added to your license
