It's surprising how often something new shows up for something old. I wrote about approach lights here: http://thanlont.blogspot.com/2012/04/night-carrier-landings-in-beginning.html
It was just brought to my attention that the F-4 had a green light on the left side of the fuselage that the LSO could use at night to determine roll attitude when he could not see the position light on the right wingtip, e.g. if the Phantom was turning left for lineup. It can be seen in this picture just below the crossbar in the A in NAVY. It looks like it is at the same waterline as the left-wingtip position light. I'm surprised that it is flush rather than protruding like a similar one is on the E-2.
