A pitch black triangular shaped craft with a red circular light at each point of the triangle.

The craft was triangular and pitch black on the bottom with  red circular lights at each point of the triangle.  It made no noise and just seemed to hover.  Cannot judge accurately how far up it was, but it was close enough so I could stick my head out of the passenger side of our semi and see it in detail.  I was just learning to drive a big truck at the time, and was in the bunk sleeping.  My trainer was so excited that she woke me up to validate this object and had me get a closer look.  There was no haze or aura at all around the object, it was just a solid black with the lights at each point of the triangle.  Do not recall seeing any lifeforms at all either. Ever since this experience, I have had eerie feelings sometimes that I am not alone.  I dont know if this is just imagination or what, but it gives me the creeps!!
