Would someone be able to provide a schematic of a circuit with a photocell for a dawn to dusk switch. The input and output will be 12 vDC. I have found circuits that reduce the output for an LED but I need the same voltage for the output.
Thank you

Here is one on thi page:

Thank you for the link that was what I was looking for. Just one additional question what is IC1? I know it is an integrated circuit/transistor but what size should it be? The schematic calls it a voltage comparator. Thank you again for your assistance.

Its something like this. The diagram is a basic circuit. This shows the outputs.
