Plastic sensor light featuring M&M's Yellow character in a thumbs-up pose. The sensor on top turns on the light when it gets dark. I haven't used it much, but I bought it about 20 years ago and it's been stored in a closet. I've confirmed that it lights up, but since it's old, please consider it without warranty. - Character: M&M's Yellow character - Design: Thumbs-up pose - Material: Plastic - Country of Manufacture: China - Manufacturer: Polyconcept USA, Inc. Thank you for looking.
