auto intensity control of street lights

Can someone please tell me that can I design a circuit for auto intensity control of street lights without using microcontroller and IC? The circuit has to reduce and increase intensity at output?

NEED ANSWER ASAP.

Hi AsimI do not think that

Hi Asim

I do not think that this is possible without using any IC; there are few circuits which work similarly without any microcontroller but they have to have some or the other sort of ICs involved in them. On a very basic note, you would need a sensor to measure the intensity in the surroundings and a driver circuit which could adjust the light bulb's intensity accordingly. Sensor could be a LDR and the driver ciruit could be based on 555 timer IC & some mosfets or triacs to deal with the light bulb. 

This might help :)
