Concluding that it's intelligent life "using lights as we do" is just a wild claim with no backing. From the evidence it's pretty obvious that it's a holographic projection sent backwards in time from humans in the future.
Here are the two source images taken at the same time by the rover's two cameras:

But of course disreputable "news" sites bring in a UFO enthusiast as their source for a quote about the possibility that there is intelligent life below the surface.

It's crazy for me to think about this in comparison to Earth. Imagine somebody dropping a robot on Earth before any known life and trying to make sensible conclusions about what the entire planet was like by only exploring 3.8 miles...
From his post:
"Sure NASA could go and investigate it, but hey, they are not on Mars to discovery life, but there to stall its discovery."
On a related note, I recently discovered that YouTube is a hotbed of dedicated quackery.
The amount of effort put into some of the "updates" and the odd intersections of religion, pseudoscience and misinterpretations of actual science are fascinating.
One of my favorite podcasts "The Skeptics Guide to the Universe" [0] does a good job of keeping abreast of and debunking some of the popular trends in wackiness.

Also, from what I read this was first noticed on a website called "UFO Sightings Daily". NASA isn't giving it any thought because there's nothing to think about.
