Yeah, I can help flesh this out more. You see, the "strange lights" at Area 69 rumor comes from a bluegreen type light near a bunker in the center right under the base. However, underneath this area in the Area 69 interior is a large room giving off a light. It is simply a case of the light leaking through the ground, because GTA is 12 years old and did not have an advanced lighting engine. The same applies to pretty much every other strange light. Just mark it on your radar and go to the exact spot in the interior and you'll usually find a light source there.
There's your answer. I've never really noticed the light, likely because i try to not get shot down.
