If you want the timing to be exact, the only option is to use the same signal the lights use. That will no doubt be near on impossible. You won't be allowed to connect to the circuit.
If you want it within seconds, you need to detect the lights turning on. This too could be quite tricky depending on the lamp type.
What you need to decide is, what is an acceptable time difference. You need to be realistic about this.
If you can tolerate around 5 mins in the winter and maybe as much as 30 mins (I don't actually know, its a guess) in the height of summer, a daylight switch is the best option.
BTW - this is a heritage lighting project for our small Arrowtown CBD.
So does this mean the area you are looking to light up will be accessible to the public, and you therefore want the timing to be exact to avoid any misconceptions that there is something wrong?
Thanks everyone for your input but now have got it sorted. Briefly, the local power contractor to Council is supplying ripple control units for each building - FOC. These will be controlled on the same circuit as the street lights.
Why work on Wednesday and stuff up 2 good long weekends

even better when it's FOC bearing in mind AFAIK they are still there property just like the meters.
