Stars are considered to be a light source because they are self illuminated. Stars are self illuminated because of the nuclear fusion occurring inside of them.
Stars are not reflectors; they emit their own light through nuclear fusion reactions in their cores. Stars generate energy by converting hydrogen into helium, which produces light and heat. Reflectors, on the other hand, simply bounce light off of their surfaces.
No, a bicycle reflector is not a source of light on its own. It works by reflecting light from other sources, such as car headlights, to make the bicycle more visible in low-light conditions.
The moon is both a partial reflector and a partial absorber of light.The only thing it's NOT is a source of light.
Sapphire doesn't create or produce light. If you can see it, then it must be reflecting light from something else.
The moon does not generate its own light; it simply reflects the light of the sun. Because it does not produce light through any internal process, it is not considered a source of light but rather a reflector of sunlight.
light source
A traffic light is a light source as it emits light to signal drivers when to stop, slow down, or go.
A light source generates and emits its own light. A reflector reflects light (i.e. light bounces off of it) from another source. Examples of light sources: The sun, the stars, a lightbulb, a flame, a red-hot piece of metal. Examples of reflectors: The moon, the planets, the ground lit by the sun.
Source light is light coming directly from a light source/emitter (i.e. a light bulb, the sun, stars, etc.). Reflected light is light coming indirectly from the light source/emitter. That could be reflected, refracted light, etc.

This is a head lamp for a vehicle, comprising an illipsoidal reflector, a horizontally oriented light source, and a lens. The reflector has forward and rear focal points and extends forwardly of the latter. The light source is at the rear focal point. The focus of the lens is at the forward focal point of the reflector. The reflector and light source and lens are proportioned to project an elliptical beam pattern having a relatively great horizontal spread. This pattern is symbolically represented by a spoke-like multiplicity of groups of overlapping images of the source.
