The illumination assembly includes a light element, a door position sensor, and a control circuit electrically coupled to the lighting element. The control circuit is configured to control an ON/OFF state of the lighting element based on one or more signals from the door position sensor. In some embodiments, the illumination assembly further includes a housing configured to house the lighting element. The housing is further configured to me mechanically attachable to the door. The control circuit may be further configured to switch from an OFF state to an ON state when the door is moved to a closed position.
