In a general aspect, an illumination assembly includes an article including a body having a first magnetic element with at least one electrically conductive surface. The illumination assembly also includes a light assembly including a housing, a second magnetic element, a light source, and a power source. A first terminal of the light source is electrically connected with a first terminal of the power source. The light assembly also includes a first electrical contact disposed on the housing and electrically coupled with a second terminal of the light source. The light assembly also includes a second electrical contact disposed on the housing and electrically coupled with a second terminal of the power source. Magnetically coupling the light assembly with the article, via the first magnetic element and the second magnetic element, electrically couples the first electrical contact with the second electrical contact to energize the light source.
