Is this a good question? … They are often referred to as CdS cells (they are made of Cadmium-Sulfide), light-dependent resistors (LDR), and photoresistors. I tested the power and found good voltage, but when I put my tester to ohm meter and touched the white wire and the conduit, it showed that there is a connection between the two. Can still ring out and receive calls . Answered! Photocells are sensors that allow you to detect light. Remove the cover and observe how long it takes for the light to turn back off.
