Exterior Lighting

We have three exterior lights on the front of our house, both on the garage and the other by our door. They are lights normal set when the house was built. My question is, is there a way to connect all three fires up an automatic timer?

I was very happy with motion sensor lighting outside, those who come on when something moves nearby. (You can define how much and for how long they stay on.)

The police recommend them as a deterrent against burglary.

It saves energy because the lights are turned on only when needed.

If you will be re-wiring, you can also do it with panache!

They are probably wired to different circuits to wiring
them to a single timer would be a major undertaking.
Much easier to invest in separate meters, (fits in
existing switch box) for each.
