When Shader is set to Mobile/Diffuse in Unity material and an image is inserted, the light disappears. How can I see it?

This is how the light is when no material is attached (normal)

This is the person who has the material attached. The spotlight is no longer visible.

↓ Material settings.

↓ It will be the image attached to the material.

↓ It will look like a directional light.

* The light settings will remain at their defaults.
