The purpose of the flashing lights is to minimise the chance of a bird strike. Also of some help to ATC. Some of the Dash 8's have been fitted for some time and some of the QF 737's are being fitted progressivly. It is all part of a trial to see if strikes are reduced as a result, comparing those in the fleet with the flashing lights against those that don't. The lights may be selected to on or flash as required. It is nothing new having been around for some years. Some of the former RAAF CT4's also had the mod. Strangly it also extends the life of the lights.
