This street light controller circuit is designed for around a single IC timer 555. This IC has been used in its bi-stable mode in the circuit. Two LDRs are also used in this circuit to differentiate between day light and dark light. During the day time this bi-stable circuit remains reset by the LDR-2 while in the night time this bi-stable is set by the LDR-1. The output from the timer IC is given to the base of transistor T-2 which drives the relay in turn Street light connections are given from the N/O contacts of the relay as shown in the figure. The number which can be connected in parllel to this circuit depends directly upon the load rating of the relay contacts.

Hi Sir, I have a lot of experience in Lighting field and interested to work with you. If you are interested , let me know some basic details so I can help you. 1) What will be the maximum load which should connected across the relay? 2) Whether the light is AC Powered or DC Powered? 3) Do you have any separate supply for the proposed design? 4) IF PCB is needed , what will be the desirable size?
