Motorcycle riders are bringing back a nostalgic trend that adds a blue tint to their tail lights—a style inspired by 1950s hot rods. The blue lens look, once seen on classic custom cars, is now popping up on café racers, old-school Harleys, and modern choppers.
How It Works
The modification involves drilling a tiny hole in the tail light and inserting a small blue lens. It’s cheap, simple, and helps bikes stand out. Some riders claim the blue contrast improves visibility in fog or low light—but it’s mostly done for style.
Federal Law Says Tail Lights Must Be Red
Despite the cool factor, the trend is not street legal in most cases. Federal regulations clearly state that vehicle tail lights must be red. Violations can result in fines up to $300, especially in states like California and Texas.
Some States Offer Loopholes
There are exceptions. States like Florida and Washington allow blue tail lights on vintage or street rod vehicles, but motorcycles must be registered as custom or classic. These vehicles are usually limited to parades, exhibitions, or club events—not everyday use.
Are Police Cracking Down?
While some riders take the risk, assuming police are more focused on dangerous driving, officers can and do issue fines for illegal lighting. Riders are reminded that aesthetics don’t override federal law.
In Other Motorcycle News
Harley-Davidson recently unveiled a wild new custom bike with glowing red tires, metal armor, and a spiked helmet, in a surprising collaboration with another brand. Fans have called it a “masterpiece.”
In a separate incident, a rider in California was caught performing a wheelie in front of police on I-80 near San Francisco. The rider fled but was later stopped by the California Highway Patrol. Officers said he eventually “made the right choice” by pulling over before someone got hurt.
Whether you’re customizing your ride or showing off on the road, law enforcement warns riders to prioritize safety over style—and to know the legal limits before modifying their bikes.
