Saw triangle dotted reddish lights from my bedroom window, which began to slowly move and change to bright light, then disappeared.

Saw a bright reddish orange lights  in a triangle dotted form. It stayed still at first, then appeared to move very slowly toward me, while looking up from my bedroom window. The lights changed to bright light, then faded away gradually, then it was gone. Within 10 minutes, now, TWO just appeared, but further away than the first sighting. Again they moved toward me slowly, getting brighter as they moved. Again they just faded away and we’re gone.
