THIS THREAD IS DEPRECATED!
This mod has been taken over by @MOARdV and is maintained in his thread here:
First things first: Big thanks for RPGprayer's "Position/Navigation Lights" AddOn, from which the Aviation Lights originated.
Additional credits go to @Deadweasel, @Why485, @GROOV3ST3R, @JDP, @J.Random and especially @MOARdV for their great help/maintenance with/of this addon.
Because I personally have my focus elsewhere and sadly do not play KSP much at this
I've recompiled this mod for KSP 1.1 (build 1196, although I don't think build number matters in this case). The link is on DropBox. Per the terms of the license, this is code originally from RPGprayer, edited by BigNose, Why485, GROOV3ST3R, JDP, J.Random, and now MOARdV. Source is included in the ZIP, same as previous versions.
