All this flashing of lights... one thing I will guarantee... you'll blind the tug driver
Can I say to all pilots. NEVER flash the nose light to attract attention.
I was departing an A319 last week at night. Standing at the nose connection, when the capt flashed the nose light about one metre from my eyes.
It wasn't just that I could not see anything, I was doubled up in pain for 5 mins, my left eye felt it was on fire. Finally managed to stand up, and the aircraft departed about 10 mins late!
Never happened to me before. At our airline it is strictly forbidden. The tow crew will just leave.
I told the crew what I thought of them, and wrote to their boss. I had a pain in my retina for 3-4 days.
