With low voltage lighting like with many outdoor landscape lights, photocell sensors tell the transformer to turn on and off based on how much light is present. For example, when the sun sets outside and it starts to get dark, the photocell sensor lets the transformer know that it is time to turn the outdoor light fixture on.

A breakdown of lighting photocell wiring
Light-sensitive components: Inside a lighting photocell, there is typically a photoresistor or a photodiode that changes its resistance or electrical current flow in response to the amount of light it receives. When it is dark, the resistance or current flow increases, while in bright conditions, the resistance or current flow decreases.
