For some, it’s not enough to decorate their homes with festive lights and decorations for Christmas. Many take it a step further and adorn their vehicles with reindeer antlers, holiday-themed wreaths and even fairy lights since Texas law doesn’t specifically prohibit it.

Driving with Christmas lights on a vehicle in Pennsylvania is illegal, authorities said. Christmas lights on cars turn heads, but a police department in Pennsylvania wants to remind drivers of the hazards.

Police in multiple states and jurisdictions are warning drivers not to install Christmas lights on their vehicle. Besides being a distraction, laws typically ban blue and red lights for non-police use.
