Are Underglow Lights Illegal in California?: 1 Minute to Understand the Law Around Underglow Lights

Underglow lights—those vibrant LED accents installed beneath vehicles—are popular for their stylish appearance and ability to make any car stand out. But if you're driving in California, legality is a legitimate concern. In California, rainbow-colored lights underneath your car may turn heads, but they might also attract unwanted attention from law enforcement. The state’s vehicle codes strictly regulate vehicle lighting to ensure road safety.

Here’s what you need to know: Underglow lights are not strictly illegal in California, but their use is subject to very specific regulations. The main rules are:

1. Any lights visible from the front of the vehicle must not be blue or red—these colors are reserved for law enforcement.
2. Lights must not flash, oscillate, or rotate.
3. Only white or amber lights are allowed at the front, and red at the rear.
4. Lights must not be distracting or create a hazard to other drivers.
5. While you can have underglow lights installed, they should be turned off while driving on public roads. They’re generally acceptable for use on private property or at car shows.

From a designer’s perspective, lighting choices often reflect the personality of a car owner and enhance the overall ambiance of a vehicle. If you’re considering integrating unique lighting features in your garage, home office, or studio (where legal restrictions aren’t an issue), you might want to experiment with modern tools like a home designer app. These resources let you play with concepts—be it innovative lighting layouts for your interiors or visualizing how ambience lighting impacts spaces—without worrying about compliance, making them a helpful solution whether you’re planning a garage renovation or envisioning a bold new room design.

Tips 1:

If you’re set on adding underglow to your car in California, opt for soft, single-color lights and install an easily accessible switch—this way you can turn them off while driving on public roads and stay compliant with regulations. And as always, consult your local DMV or law enforcement for the latest legal guidance before making permanent modifications.
