Adding a security light in a circuit acting as a switch .

[Paul winter]

I have lights around my drive and thinking about putting a small security light in the circuit to not only flood the drive with more light but also to switch on other lights in the circuit . All the lights are LED so the load isn’t that high but what would be the best way to wire a standard security light to do this please ? Or is there a better way to do this ? I done a quick sketch to hopefully explain it better. Regards

Depends whether you can get at the internal wiring.

Anyway a separate sensor/switch would be better - then the wiring will be obvious won't it?
