I want to talk to you about the importance of Navigation lights 
and in relations to other aircraft 
-Green Steady= Right tip: can seen from Front and Right side
-Red Steady= Left tip: can be seen from Front and Left side
-White Steady= pointing backwards: can only see back and partially form sides
*All these lights can be seen from Top and Bottom as well.
-Blinking Red or White on Top/Bottom or both = Anti Collision Lights:
These let other people know that you are there, your engines are running and to keep distance from the aircraft.
*Military Aircraft have special Formation Lights 
These are used specifically in Formation flying at low light and night.
These help a lot in understanding where an aircraft is flying when looking at it from afar.
If you look at any aircraft flying over your city, you'll probably be able to see these and tell where their heading in relation to your position :)
(i'm saying probably because sometimes these are not used during day time in the Private and Military sectors)
in MP it's hard to know sometimes if an aircraft is flying towards you or away from you, especially when a lot of people are flying around and there's a lot of Landings in one airfield.
I just figured I'd share the info for people who don't understand what are those lights, and also to make life easier when flying with other people.

Now all we need if for lights to work in MP :\
Check out my other tutorials:
Runway Numbers.... What How and why
Traffic Patterns... Left, Right, up and down
Radio calls, how to Communicate as a Pilot in command.
Uncontrolled Simpleplanes Class G Communications... wait what?
If you have any questions, don't be afraid to ask me :)
P.S.
I'm thinking about making another one about Airport Traffic Patterns and basic Airport operations, Let me know in the comments if you'd like that.
I screenshot the diagrams. Very important to know if you are looking forward to a career in aviation!
@Freerider2142 ok!
@Lahoski107 on it, Traffic patterns are next up :)
@Freerider2142 keep doing these!
Make more of these. I love how informational it is.
Ok
@Freerider2142
Hopefully someday. It would take a lot of money to change now. The main problem, is not that we cannot tell the lights apart, it's that the FAA doesn't realize that we can. Not to go on a rant, but I tend to use the shades as reference. The lighter color is green. It's fun. Not. But I can!
If you look on the picture above, you can see that the green in a lot lighter. That helps, a lot.
@MrTyTheGreat these lights were setup in Naval ships and such a long time ago, before they took into consideration Color Blindness.
Maybe in the Future rules Colors and regulations will change to fit everyones needs.
I'm red/green colorblind, as with my brother. This will make it very hard for us to get any job related to aviation, because of these lights. By brother has his license and cannot fly at night because of the colorblindness. The worst part is, both of us can tell them apart, but oh well.
@Jetpackturtle Awesome! your welcome :)
Thank you!
@Vayloz Lights are positioned the same on all aircraft, so they will be placed the same on a flying sing.
sometimes there's no spot for a specific light, but as long as it covers it's "area" it doesn't matter..
I.E.: In the F-15 the Rear lights are on the vertical stabilizers, Left is White Position/NAV light and Right is Red Anti Collision Light
Never knew of formation lights
I already put realistic lights on my civilian planes, but this has taught me some more. Thanks!
Use overload for strobe lights
@Razor3278 Awesome!
happy it helps :)
I've been enlightened by this post. Thanks!
