Narrative:
At AB45Z the taxiway and runway lights began to vary intensity and turn on and off by themselves!! Aircraft (about 25-30) were taxiing, taking off or landing. My shift ended 45 mins later and the problem was still unsolved. This creates a very dangerous situation. This airport has had a recent history of lighting problems. Callback conversation with reporter revealed the following information: reporter stated that this situation lasted for 4 to 5 days and was very disturbing. Night departures and arrs would suddenly find no lights, or continuously dimming lighting. Reporter has no idea what the cause was. The allegheny county airport management is responsible for all lighting except the approach lights, and reporter has been unable to find out what occurred. He does know there was some construction going on at the time. He hopes the information will be retained in the database because he feels the ucr that was filed will be held for a while, and then he will be notified that the situation is ok now and that will be the end.
