For some people, Christmas lights on houses, shrubs and trees falls short of all-out festive — they have to deck out their cars as well.

The nationwide automotive site Jalopnik calls Christmas car lights a trend in overdrive, but also “dumb and probably illegal.”

In fact, Connecticut State Police say attaching colored lights to a vehicle does violate state law.

“Generally speaking, decorating a private motor vehicle with Christmas lights is illegal,” state police said.

State police said the two Connecticut statutes the decorative lights could violate each carry a $92 fine.

“Generally speaking,” state police said, “only white, amber or red lights are authorized to be displayed on a privately owned motor vehicle in reference to headlights, marker lights and tail lights, respectively.”

However, state police said they don’t have “any recent examples of these statutes being applied.”

A search for “Christmas lights on cars” on Google or social media sites and dozens of images emerge of SUVs, sedans and pickup trucks cruising roads and highways in dazzling, multi-colored illuminations.

The dazzle is part of the problem, police around the nation say. The bright lights can confuse other drivers, who may miss turn signals and brake lights amid the hood-to-trunk radiance. The Wyoming Highway Patrol posted a photo of a cruiser behind a lit-up car with the warning, “while this might look cool and be festive, we would like to remind you that it is illegal.”

Also, according to Jalopnik, the taped-on lights have damaged cars as glass bulbs resting on paintwork “have a habit of flapping about in the wind while you’re driving, covering some cars in tiny scratches.”

But what if nobody cares about the paint job? Last Christmas, some Denver residents found a festive way to highlight neighborhood blight, decorating an abandoned Chevrolet Impala with tinsel spelling, “TOW,” a red bow on top and a row of red stockings on the trunk, Fox 31 TV reported.
