Are LED Light Bars Legal in California?

LED light bars have become a standard upgrade for off-road vehicles, trucks, SUVs, and commercial fleets thanks to their superior brightness, energy efficiency, and rugged design. However, California has relatively strict vehicle lighting regulations.

For automotive distributors, retailers, installers, and fleet buyers, understanding these rules helps avoid legal risks, customer complaints, and compliance issues.

This guide explains how LED light bars are regulated in California and how B2B businesses can ensure compliant sales and installations.

Are LED Light Bars Legal in California?

Yes—but mainly for off-road use.

In general:

LED light bars are legal to own and install.

They should not be used on public roads unless compliant with state lighting regulations.

Off-road auxiliary lights typically must be covered when driving on highways to prevent glare.

This distinction is important for dealers and installers selling to California customers.

Key California Lighting Regulations to Know

1. Limit on Forward-Facing Lights

California vehicle regulations generally restrict the number of forward-facing lights that can be illuminated simultaneously.

This includes:

• Headlights
• Auxiliary driving lamps
• Fog lights
• Spot lamps
• LED light bars

Exceeding allowed limits can result in citations.

2. Off-Road Lights Must Be Covered on Public Roads

Light bars designed for off-road use:

• Should remain off when driving on public roads
• Often require opaque covers when mounted above bumper level

Providing covers with products helps customers stay compliant.

3. Approved Light Colors

Typical front vehicle lighting requirements include:

• White or amber/yellow allowed
• Red or blue restricted to emergency vehicles

Non-compliant colors may lead to penalties.

4. Beam Aim and Glare Control

Improper installation can cause:

• Excessive glare
• Reduced road safety
• Increased legal risk

Professional installation guidance is strongly recommended for B2B customers.
