The Consumer Product Safety Commission ("CPSC" or "Commission") is issuing a final rule to specify that seasonal and decorative lighting products that do not contain any one of three readily observable characteristics (minimum wire size, sufficient strain relief, or overcurrent protection), as addressed in a voluntary standard, are deemed a substantial product hazard under the Consumer Product Safety Act ("CPSA"). Additionally, the Commission is making a technical amendment to reformat incorporations by reference in this part.
