According to Aircraft Rules,The navigation lights (Red and Green and strobe lights) must be 110 degrees and the tail navigation lightshould be 140 degrees.U can see the attachment.Not something major.Basically it means that no one can see the navigation and strobe lights from behind except the tail navigation light.http://forums.avsim.net/user_files/94301.jpg

May I ask what you are trying to get at?Luckily, this is a sim and the direction of the NAV/Strobe lights doesnt really matter, since no one else sees your aircraft. :)

I find that a little hard to believe, other wise...What would be the point in making them different colours?If what you say is true, then you can make both nav lights green. If the plane is flying left to right across your field of view you will see:WHITE - GREENIf it is flying right to left you will see:GREEN - WHITEIf it is flying away you will see:WHITEIf it is flying towards you, you will see...GREEN - GREENThe reason they are different colours, RED/GREEN, is from water navigation, you can tell by the orientation of the lights, which way the vessel is traveling in relation to yourself.I believe the nav lights (red and green) should be seen from almost all directions, unless shadowed by the plane... which also tells you something about it's direction of travel relaitive to you.Of course I haven't actually read the rules.PS if I remember correctly, when a plane flies over my house at night, I can still see the nav lights, red and green as it flies away.. from behind. Outside of your forward pointing 110 degree visibility on the diagram.Further still... it is very easy to place yourself on your diagram, where in effect you wouldn't see one single light at all.

I'll tell you why.First of all.If you are sitting in the cockpit.The right wing will have green light and the left wing will have red light.If you are coming head on to another aircraft.Say both the aircrafts DONOT have TCAS installed.If you are in one aircraft and are going head on to another aircraft you must turn in the direction where you see green light of the other aircraft to avoid collision.So basically you must turn to the right to avoid collision.Never turn towards the red light of the other aircraft.YOU WILL KILL YOURSELF.Now the other part,if you are following an aircraft (you dont know that),how would you know in which direction the aircraft is flying.So if we dont see the lights from behind it means that the aircraft is moving in a direction similar to your path.This is just for your information guys.As we have TCAS-II working in PMDG just wanted everyone to know that."As Real As It Gets".

You are correct about the red and green lights that are supposed to be visible to the front and sides.The white strobes on wingtips, however, are typically visible through a 180 degree range, as their purpose is not to give you any sort of orientation, but just to say "something's out there".Same thing applies to the beacon on the tail of a cessna or on the top and bottom of the 737.FWIW, my former mooney had no light on the tail at all, instead it had a tail-facing steady white light on each wing tip, a strobe light, and then the red or green nav light all mounted in a single housing.
