A Brief History of Neon Lights

Before diving into the legalities, it's essential to understand the allure of neon lights. Invented in the early 20th century, neon lights quickly became synonymous with progress, modernity, and the future. Their unique ability to glow in the dark made them a favorite for advertisers, nightclubs, and eventually, car enthusiasts.

California's Stance on Neon Lights

California, known for its sun-soaked beaches and progressive culture, has specific regulations when it comes to neon lights on vehicles. According to the California Vehicle Code, while neon lights are not entirely illegal, there are certain restrictions that vehicle owners need to be aware of:

Color Limitations: The use of blue and red lights facing forward is prohibited. These colors are reserved exclusively for emergency vehicles.
Visibility Constraints: Neon lights should not be directly visible from the front of the vehicle. This means they should be installed in a manner that their direct light does not distract oncoming drivers.
Functionality: Flashing, oscillating, or rotating lights can be misleading and are not permitted.

Research: Before making any modifications, research both state and local regulations. Laws can vary, and what's permissible in one area might be illegal in another.
Professional Installation: Always opt for professional installation. Experts will be aware of the legal requirements and ensure that your vehicle remains compliant.
