Counterfeit products are typically priced lower, making them attractive to shoppers looking to save a buck

What looks like a great deal, probably is too good to be true. Be on the look out for any electrical lighting products this holiday season. Counterfeiters in recent years have become increasingly savvy about reproducing holiday lights with logos purporting to be from independent safety-certification laboratories, industry and safety groups say. Such products also may have fake trademarks of reputable manufacturers.

These lights tend to fail and cause electrical fires in your home. No federal law mandates third-party testing for electrical products, but many retailers require it. The Consumer Product Safety Commission advises consumers to look for safety certification on products like holiday lights and extension cords.
