What items contain a LDR?

Light-dependent resistors (LDRs) are commonly found in various devices that rely on light detection. These include automatic street lights, solar garden lights, light-sensitive alarms, and cameras with automatic exposure settings. Additionally, LDRs are used in toys that respond to light and in light meters for Photography. Their ability to change resistance based on light intensity makes them useful in applications where light levels need to be monitored or controlled.
