Try verify your program using push button, is the photo diode digital? If it is analog, use a potentiometer/variable resistor to replace it. Play around with the potentiometer and push button with your program, if the program does not response correctly, you need to debug the program, reduce the complexity of program until it works. Only after that, add more code and verify again.

According to your code,

LED2 is always ON unless PIR sensor is triggered when Light is OFF
LED will be only on then PIR sensor is triggered when the light is OFF

If this is not the sequence that you want, better check your coding logic.
