Are Light Bars Legal in California?: 1 Minute to Understand the Legal Status of Light Bars in California

In California, the legality of light bars—especially LED light bars commonly installed on vehicles like trucks, SUVs, and off-road vehicles—is a frequently raised question. According to the California Vehicle Code (CVC), light bars are not outright illegal, but their use is highly regulated to enhance safety and minimize glare for other drivers.

Here are the key legal points:

1. Off-road Use Only: Most aftermarket LED light bars are approved for off-road use only. Driving with them turned on while on public highways or streets is prohibited.
2. Covers Required: If your vehicle is equipped with an off-road light bar, you must have opaque covers over the lights while driving on public roads (CVC Section 24411). Failure to use covers can result in a citation and fines.
3. Mounting Height: The height and position of auxiliary lights must comply with state regulations. Generally, they should be mounted no higher than the headlights and no lower than 12 inches from the ground to the center of the lamp.
4. Color Restrictions: White and amber lights are usually allowed. Blue and red lights are reserved for emergency vehicles.

As a designer, I’m always considering both function and compliance when integrating vehicle accessory lighting. When working with residential or garage spaces, home lighting design must also abide by local codes, ensuring both beauty and safety. Selection, placement, and brightness all play critical roles—inside and out.

Tips 1:

If you’re planning an outdoor or garage workspace, choose lighting that’s approved for both use and placement. Always check your city or county’s regulations, as local rules can be stricter than the state’s.
