About 315,000 electroluminescent night lights were distributed nationwide free of charge under various company names as promotional gifts from October 2001 through November 2009. They were manufactured by Molenaar LLC of Willmar, Minn.
No injuries have been reported, but Molenaar has received four reports of night lights melting, which could pose a hazard of either a shock or a burn.
Consumers were advised to throw the night lights away.
The night lights involved in the recall include model No. 2019, which is shaped like a house, and model No. 2017, which has a square shape with a rounded top edge. The nightlights, which glow green when plugged in, have "71980 U.S.A." molded in the back panel of the light.
