Answer
The stars do not glow when the light is off. When the lights are on. the atoms in the stars are absorbing energy and the electrons remain in their higher energy levels. When the lights are turned off. electrons are emitted, which is why you see light. The electrons drop to lower energy levels. Once the electrons reach the ground state, the light will not longer persist.
