Are LED lights or underglow lights legal on a motorcycle in Michigan? In this Motorcycle Legal Minute™, Jason Waechter, The Motorcycle Lawyer®, explains Michigan motorcycle lighting rules, why underglow can create equipment violations, which colors can cause legal problems, and why riders should be careful before using aftermarket lights on public roads.
Do not assume LED or underglow lights are legal on a Michigan motorcycle just because they are sold as motorcycle accessories. The public-road question depends on whether the light is required or permitted, where it is visible from, whether it flashes, and whether it uses colors restricted for emergency or required vehicle lighting.
For related equipment issues, review Michigan motorcycle tickets, fines, and points.
Lighting questions can involve equipment rules, visibility, ticket defenses, and crash facts. If an insurer or driver argues that motorcycle lighting contributed to a crash, save photos, video, ticket paperwork, lighting setup details, and witness information.
The Motorcycle Legal Minute™ was created by Jason Waechter, The Motorcycle Lawyer®, to explain Michigan motorcycle law in a short and easy-to-understand way.
Custom LED lights and underglow lighting can make a motorcycle stand out, but Michigan riders need to be careful. Motorcycle lighting laws are not just about appearance. They are about what lights are allowed, where they are visible from, what color they display, whether they flash, and whether the motorcycle is being operated on a public road.
The safest general rule is this: do not assume a light is legal just because it is sold online, installed by a shop, or commonly used at bike nights. Michigan law can still restrict how that light is used on public roads.
Michigan law takes a restrictive approach to extra vehicle lighting. Under MCL 257.698, a vehicle operated on Michigan highways generally cannot be equipped with a lamp or reflector unless it is required or permitted by the Michigan Vehicle Code, meets applicable federal standards, or is both covered and unlit while on the highway.
That matters for underglow because underbody lighting is not treated like a normal required motorcycle headlight, taillight, brake light, or turn signal. Even if the color seems harmless, the bigger issue may be whether the light is permitted at all while the motorcycle is being operated on a public road.
In practical terms, underglow lights may be safer to use for display purposes on private property, at shows, or while parked, but riders should be cautious about riding with underglow illuminated on Michigan public roads.
Color matters, but color alone does not make motorcycle underglow legal. Michigan law includes specific restrictions based on the direction from which a light is visible.
The important point is that riders should not think, “As long as it is not blue or red, I’m fine.” Michigan’s equipment law is broader than that. If the light is not required or permitted and it is not covered and unlit while riding on a public road, it may still create a violation.
Using underglow while the motorcycle is parked or displayed on private property is different from operating the motorcycle on a public road with the lights illuminated. Many riders use LED lighting at shows, bike nights, private events, or in parking areas.
The public-road issue is where the risk increases. If the motorcycle is operated on a Michigan highway with underglow or extra LED lighting turned on, the rider may be stopped and cited if the light is not legally permitted.
A practical safety step is to install a separate switch so underglow or accessory lights can be turned off before entering public roads.
Flashing, rotating, oscillating, or strobe-style lights are a major problem for civilian motorcycles. These types of lights can confuse other drivers and may be associated with emergency vehicles, road service vehicles, or other authorized uses.
For most riders, the safest answer is simple: do not use flashing, strobing, rotating, or oscillating accessory lights on a motorcycle while riding on Michigan public roads.
Yes. Illegal motorcycle lighting can lead to an equipment violation or traffic stop. A rider may receive a civil infraction, be required to correct the equipment issue, or face additional scrutiny during the stop.
Even if the fine is not large, the bigger concern is that equipment violations can create unnecessary problems. A lighting stop can lead to questions about insurance, endorsement status, registration, helmet use, exhaust noise, or other motorcycle equipment issues.
Possibly. If a motorcycle crash happens while illegal or questionable lighting is in use, an insurance company or defense attorney may try to use that against the rider.
They may argue that the lighting confused the other driver, distracted traffic, made the motorcycle harder to interpret, or showed that the rider was not following equipment laws. That does not mean the argument is valid in every case. It also does not mean an equipment issue caused the crash.
But after a serious motorcycle accident, insurance companies often look for ways to shift blame onto the rider. Avoiding questionable lighting on public roads can remove one more argument they might try to use.
If you want custom LED lighting or underglow on your motorcycle, take a careful approach before riding with it on public roads.
If there is any doubt, keep the underglow off while riding on Michigan public roads.
Motorcycle lighting is only one part of Michigan’s motorcycle equipment law. Riders may also want to review these related topics:
The takeaway is this: Michigan riders should be very careful with LED underglow and aftermarket motorcycle lighting. A light may look great, but that does not mean it is legal to use while riding on public roads.
Blue lights, red lights visible from the front, flashing lights, strobe effects, and extra lamps not required or permitted by law can all create problems. If you use underglow for show or display, keep it off before riding on Michigan highways unless you are confident the setup is legally permitted.
