White light duplicating itself in a pattern

While driving east on the I-10 between Quartsite and Salome, after passing the mountains, I looked north and seen a bright light in a fixed position in the sky. It split and an exact duplicate of it moved west of it and immediately stopped. The original light then disappeared. I lowered my window to make sure it wasn't a reflection and at that time, the new positioned light then split up and did the same exact thing, duplicated itself and the prior light disappeared as well. This continued for about 10 seconds and then it completely disappeared. I travel this area often and can confirm it wasn't on a mountain and was in the sky. It appeared to be a mile away but was hard to judge distance. The duplication it made was in a perfect pattern. The only time I noticed movement was when it was duplicating. Otherwise it appeared to be paused in a fixed position. The only thing I can compare this to is the intro of older James Bond movies, where there is a white ligh! t duplicated across the screen. Sort of similar but with more of a pause.
