The green light should be a indication that this APU is turn on. (Not running.)
See if your colleague is in the cockpit, and you are behind the APU doing some work, you would certainly like to know whether this APU is on and ready to ignite.

Great pic! And indeed El Al has missile defense systems on all of its aircraft although I don't know where it's installed so I'm not sure if the green light has something to do with it.

Cool photo..I doubt very mutch that it has any surface to air missile defence systems on a commercial airliner. Lol I hope that guy was kidding.

The APU inlet is on the top-right side of the fuselage right infront of the apu, if I'm not mistaken. hardly ever saw such a clean 747 tail cone...

Excellent detail! The APU wouldn't normally be operated during the flight, the main engine generators provide more than enough power (and heat!). The inlet for the APU is through a small hatch positioned on top of the fuselage next to the base of the tail fin.

I think that green light is actually a laser for defeating portable surface to air missiles. It would make sense since the APU releases heat and the missile could possible lock onto the heat signature. But then again I may be wrong though.

Oh, if it's on, you will know it. no green light needed!

Wow! That really shows me the size if the 747...and they've even thought of putting a green light on, I'm guessing to tell someone the APU is in use?
