Motorists could land themselves in extra trouble if they wrap blue flashing lights around their vehicle.
This could be seen as impersonating an ambulance, police car or another emergency service vehicle which is against the law.
Experts at Family Car Deals explained: “Decorating your car for Christmas might seem fun, but some accessories come with hidden risks.
“Trendy interior LED lights, purchased nearly three million times, could violate UK lighting regulations if improperly installed, leading to a £1,000 penalty.”
Only white lights are permitted at the front of a car, with red lights only allowed at the rear.
Meanwhile, LED lights should not cause discomfort or dazzle other road users as this could become a safety risk.
Extra lighting fitted inside a car should not flash as this could cause a major distraction to other road users.
However, specialists have warned that it’s not just LED lighting which could give motorists a headache this Christmas, with other decorations also a risk.
Family Car Deals added: “Another festive favourite, seatbelt covers, ranked seventh in popularity with over two million sales and pose a surprising safety hazard.
“Oversized plush designs, though cosy, can compromise seatbelt positioning, making them less effective in collisions and increasing the risk of injuries.
“For parents, unbranded child car seats sold on Temu pose an even greater concern. Despite their bargain appeal, these uncertified seats, 293 of which have been sold, don’t meet essential UK safety standards, putting little ones at serious risk in accidents.
“The findings remind us that prioritising safety over style or savings is especially critical during the busy holiday travel period.”
