Allright what he said in the english version:
I'm going with the british variant:
First of all place one object called JP-3 Generator 15kW or something like that on the map.
Now place say, 3 british 90cm or 150cm searchlights around the generator...
Now place the AI Anti-Air object and set radius say.. 150 and zoom out so you can see the radius. Now make sure all your ground objects are within that radius, if not either:
Move the objects
or
Increase the radius.
Now once you have those set up, look into the parameters of the Anti-Air and find the script called PowerOn.CPP and select it.
Now click the generator unit and find the set target button, click it on the anti-air AI unit and you should see a yellow line between the generator and the AI unit.
Now if you launch the mission the searchlights should work! They seem a bit bugged though because they have very limited view distance and pop up when you are really close to target. Also they didn't seem to light up the aircraft very well.
Let me know if this solved it for you
