In Michigan, light bars on cars are subject to specific legal restrictions that mainly govern their placement, color, brightness, and usage on public roads. Generally, light bars must be mounted below 42 inches in height and comply with brightness standards to be street legal. Use of flashing, oscillating, or rotating lights in colors associated with emergency vehicles is prohibited except for authorized vehicles.
What Are Michigan’s General Laws Regarding Light Bars on Vehicles?
Michigan law restricts aftermarket vehicle lighting to ensure road safety and prevent driver distraction. Light bars or any auxiliary lights must not:
-
Emit colors reserved for emergency vehicles (blue, red, or flashing amber, except in certain authorized cases).
-
Be installed in a manner that causes glare or impairs the vision of other drivers.
-
Be mounted higher than 42 inches from the ground.
-
Create flashing, rotating, or oscillating light effects when the vehicle is in motion.
These rules stem from Michigan Vehicle Code, particularly Section 257.698, aimed at regulating vehicle lighting for public safety.

How Does Michigan Regulate Light Bar Colors and Flashing Lights?
Michigan strictly prohibits the use or possession of flashing, oscillating, or rotating lights of any color on private vehicles on public roads, except for authorized emergency or service vehicles. The allowed aftermarket colors for front lights are white or amber, and for rear lights, red or amber.
Light bars emitting blue or red colors are associated legally with law enforcement or emergency vehicles and are illegal for civilian use. White or amber light bars are generally considered permissible, provided they meet mounting and brightness criteria.

Which Light Bar Mounting Positions and Height Are Legal in Michigan?
Light bars must be mounted below 42 inches from the ground to be legal for on-road use in Michigan. This height restriction reduces glare for oncoming traffic and aligns with headlight standards.
Mounting light bars above this height or in locations that interfere with the vehicle’s required lighting (headlamps, turn signals) can result in fines or citations. The goal is safe illumination without distracting or blinding other drivers.
When Can Light Bars Be Used Legally on Michigan Roads?
Light bars can be legally used on Michigan public roads when:
-
They are white or amber in color, positioned below the 42-inch height limit.
-
They are not flashing or oscillating.
-
They comply with brightness limits and are directed properly to avoid glare.
-
Used as auxiliary or off-road lights supplementing, not replacing, legally required vehicle lighting.
Many drivers resort to using light bars only off-road or on private property where Michigan lighting laws are less restrictive.
Are There Penalties for Illegal Use of Light Bars in Michigan?
Violations of Michigan’s vehicle lighting laws, including improper use of light bars, can lead to penalties such as:
-
Traffic citations or fines.
-
Orders to remove or disable non-compliant lights.
-
Potential vehicle inspection failures.
Severe violations involving impersonating emergency vehicles via color or flashing features could result in criminal charges, including arrest for false representation.
How Does Michigan’s Vehicle Code Address Emergency and Service Vehicle Lighting?
Emergency vehicles, construction equipment, and authorized service vehicles in Michigan are permitted to use amber, red, blue, or flashing lights as specified in Sections 257.697, 257.698, and related statutes. These vehicles have exemptions reflecting their roles in public safety, maintenance, and emergency response.
Private citizens may not install or activate these colors or flashing patterns on their vehicles, ensuring clear distinction between emergency personnel and civilians.
Could Using Illegal Light Bars Affect Insurance or Vehicle Inspections?
Yes, using illegal light bars on your car can affect:
-
Insurance coverage, as modifications violating state law may lead to denied claims.
-
Vehicle safety inspections, particularly if auxiliary lighting is deemed non-compliant.
-
Liability in accidents where illegal lighting contributed to visibility issues.
It’s critical to adhere to Michigan regulations to avoid such complications.
What Are the Best Practices for Compliance When Installing Light Bars in Michigan?
To comply with Michigan laws when installing light bars:
-
Choose white or amber light bars designed for on-road use.
-
Mount the light bar below 42 inches from the ground.
-
Ensure the light bar does not flash, rotate, or oscillate.
-
Use high-quality lighting that meets brightness and beam pattern specifications.
-
Avoid interfering with factory-installed headlights, turn signals, or brake lights.
-
Consult local authorities or vehicle inspectors for state-specific guidance.
