Light Bars & LED Lighting

Headlight & Taillight Tint
Status: Illegal | Headlight Tint in Kansas
Kansas strictly prohibits modifications that compromise lighting effectiveness, including tinting or covering headlights and taillights. This ban exists for safety reasons, as proper headlight and taillight visibility is crucial for both your ability to see and other drivers' ability to see you.

Exhaust Noise
Status: Conditional | Exhaust Noise in Kansas
Kansas regulates exhaust noise with specific decibel limits and prohibits excessive or unusual noise from modified exhaust systems. This dual approach gives law enforcement both objective measurement standards and subjective authority to cite particularly disruptive exhaust modifications.

Aftermarket Exhaust
Status: Conditional | Aftermarket Exhaust in Kansas
Kansas allows aftermarket exhaust modifications provided they include proper muffling and maintain required emissions equipment. Key requirements include proper muffling to control noise levels and retention of required emissions control equipment.

Wheel & Tire Protrusion
Status: Legal
Kansas has no fender-coverage, mud-flap, or wheel-protrusion statute for ordinary vehicles. See Wheel Protrusion in Kansas for the full breakdown. Get the exact limits, statute citations, and a printable PDF in your compliance report.
Underglow Lighting
Status: Conditional | Underglow in Kansas
Kansas allows underglow lighting with color restrictions for public safety, prohibiting certain colors reserved for emergency vehicles. Safe underglow colors include white, amber, green, and purple, while avoiding flashing patterns that might be confused with emergency vehicle lighting.

Window Banners
Status: Conditional
Sunscreening is allowed along the top of the windshield only and may not extend below the AS-1 line; it must be non-reflective and may not be red, yellow, or amber. Because the material must be transparent, a printed or opaque banner is not legal in Kansas — only a clear tint band. See Window Banners in Kansas for the full breakdown.

License Plate Frames
Status: Conditional | License Plate Frames in Kansas
Kansas allows license plate frames with visibility requirements, ensuring frames cannot cover or obstruct the license plate itself.
