I went to see the lights about 7 years ago. I'm not sure what made me think of them today, but I woke up and was just reminiscing on past memories and got curious about what the lights really were after thinking back on my experience there. I have to say after looking at the google maps and geology of that lookout point, and the old 45 road, it seems almost overwhelming to say it is cars; However, up till today there has been almost no doubt that it was something unexplainable, and not man made. I have to add also that that video posted in this thread does not even compare to the light that I witnessed.
The light appeared at around 1:30-2:00 am it was pitch black. It was only one large sphere of very bright white light that first began to shine at the ridge of the other hill across from the lookout. It was certainly anything but stationary. It moved in wavy, bobbling, very unrigid movements as it started descending down the hill. It then bounced it's way back and forth continuously getting closer to us, but for the most part it seemed to just linger around 75 to 50 percent of the way between the ridge and the observing point. Let me clarify this a bit, there is nothing but forest on either side: deep, dark, thick, nothing for miles woods, and the light is dancing around inside of them. It started at the ridge, but it moved from there quite quickly. Anyways, my one friend, my cousin, and I were all in my car, and after about 10 minutes or so of watching this light dance around the forest we got kinda bored. So being 19 and cocky as I was then, I decided to blare my horn at it a good nine or ten times. Mocking the so to speak spirit, or what ever it was they told me before we had made the trip out. Immediately the light straight bolted towards us. I couldn't make this up if I tried. I swear that for whatever it's worth, this is what happened. It just bounced it's a$$ really really fast from the mid forest area straight to my car. The damn thing was bouncing around so close to the observer area we all just freaked out. I dropped my car into reverse, my buddies screaming, and must have peeled out to just get back from the thing. It's light completely illuminated my car, and was shining directly into my windows very brightly. After getting a decent distance back from the ridge it just disappeared. We pulled the car forward and parked again, but the light was gone. So we waited around, and about 15 minutes or so later the light came back and bounced down the hill back to it's general forest area where it had lingered before.
We didn't try our luck with the horn anymore, and after observing the light bounce around some more we took off. By the way again it is anything but stationary, it moves closer and further and seems to bounce to the left and right a bit, it even crosses the side of the old road path it's on. It was certainly unexplained to my eyes. I can only suggest checking it out for yourself, because none of the videos I have found even come close to looking like the light I seen. It did not resemble a beamed light or lamp at all.
