The strobe will be triggered by using the radio. Following a mike key, the strobe will fire for 30-60 seconds. If you loose sight of the field, key the mike again.
I guess the lights do not cut on final, just the 30 seconds time out.
There are lots of strobe units available, and selecting a good one out of the many I have found is the last job, everything else is pretty much ready to go.
Here are a small selection :

Radio triggering gear is available from the U.S. but costs A LOT and switches mains (which we don`t have).
I have designed all the stuff from scratch to run without mains.....
