Hi bobby,

In two LED's one which is connected to the R3 resistance is power LED it is to indicate whether the circuit is powered or not. And LDR and LED is not connected to the negative input of LM324. only LDR output is connected to the 7th pin of LM324 and led is connected to the Ground not with ldr and 7th pin of LM324.
