Huh?
This ain't new, pulsing landing lights ( yes their correct name ) have been fitted to Aircraft and Helicopters for years. First time I saw it was on a SWA 737 over 15 years ago.
Qantas has them on 737's and Dash 8's
Their 737's even have pulsing Logo lights.....now that's crazy!!!
They are to make the Aircraft more visible to Humans and Birds...
