I seen two stationary lights that were orange, gold, yellow, silver, white, flickering and stationary lights that slowly disappeared, the right one before the other. i was traveling westbound on northern boulevard heading towards 303 when i noticed the lights. when i gotten on the 303 the lights continued to stay at the same height, they did not move left or right either. i shot some video of the lights because it was out of the ordinary for there is a lot of air traffic around the phoenix area. i had exited route 303 at glendale boulevard in pulled over to shoot the video. as i was shooting the video, the right light slowly disappeared and then the left about 30 seconds later.
