What Underglow Is Illegal In California

Don't Let Your Ride Get Busted by the Brightness Police: A (Mostly) Comedic Look at Underglow in California

Ah, underglow. Those flashy beams of light that make your car look like it escaped from a Tron convention (or maybe just witnessed a killer light show). But before you unleash your inner neon warrior on California's streets, there are a few things to consider, otherwise you might find yourself explaining your technicolor ride to a less-than-thrilled officer.

Red Up Front? Big No-No

California likes things clear-cut, especially when it comes to car lights. Red lighting is a giant NOPE at the front of your vehicle. Why? Because red lights are for brake lights, buddy, and confusing other drivers is a recipe for disaster (and a possible ticket). Imagine cruising down the highway, and suddenly the car ahead of you looks like it's hitting the brakes...but it's not! Talk about a heart attack on wheels.

Embrace the Rainbow (Almost)

Here's the good news: California lets you rock most other colors for your underglow. So, wanna bathe your car in a soothing ocean blue? Go for it! Feeling a burst of sunshine yellow? No problem (as long as it's not blindingly bright, we'll get to that in a sec). Just unleash your inner artist, as long as red doesn't crash the party in the front.

However, a word to the wise: Avoid any colors that might mimic emergency vehicles (think cherry red and cobalt blue). You don't want to accidentally trigger a high-speed chase because your car looks like a disco ball with a police siren complex.

Don't Be That Guy (or Gal) With the Blinding Lights

California has a thing about light pollution. They don't want your underglow to be the automotive equivalent of a supernova. The law says the light can't be super strong (less than 0.05 candela per square inch, to be precise). In layman's terms, it shouldn't be a beacon visible from outer space.

Remember, the goal is to have a cool underglow, not to blind oncoming traffic. Think mood lighting, not a searchlight.

Size Matters (Sort Of)

There's also a limit on the size of your underglow extravaganza. Unless your car is authorized to display signs (think taxi or rideshare), the law says the lighted area can't be bigger than 720 square inches. That's about the size of a large beach towel, so you've got some room to play.

But hey, a little underglow goes a long way. You don't need to turn your car into a rolling billboard to make a statement.

So, Can You Underglow in California?

The answer is yes, but with some limitations. Stick to the guidelines, avoid the forbidden red at the front, and don't be a jerk with blinding lights, and you'll be cruising in style (and legality).

Remember, a little underglow can add some personality to your ride. Just don't let it land you in hot water (or under the flashing lights) with the law. Now get out there and show off your not-so-secret disco on wheels (responsibly, of course)!
