Series of lights appear on ridge

Lights on the ridge near KSOX Doppler Radar Tower and Black Star Canyon.  Unusual lights high in the sky that seemed to be a small line of blinking lights.  Viewed through 2nd story apartment window.  Noticed it was not moving closer or further away as I was in the kitchen and where the lights were coming from were high at the very top of the ridge. Often just a single light but sporadic moments of multiple lights, sometimes fading in and out.  One time 3 lights in equal distance from each other were twinkling on.  Then later it was two lights but closer together.  At the brightest intensity, it was quite bright.  Not unlike when you'd see an airliner's lights directly on.
 Activity ceased around 11:35pm.  The ridge is dark now.
