UFO Sighting in North Richland Hills, Texas on June 28th 2015 – Three objects round in size with flashing light traveling in a triangle form hovered for about 20 minutes before slowly moving away

I was taking my dog out and looked up, saw three objects just hovering there. Thought they were planes before I noticed they were not moving. A plane came by and at that point I knew they weren't planes. The light were in the center of the objects moving around them quickly, red, green, blue and white. I tried to snap sits with my phone but did no justice. Grabbed my other camera and turned the flash on, when I did that they appeared to slowly go out SE at a very slow pace then stopping again maybe a half mile out.I text a friend of mine to see if she were up and had her call me. Her and her son's went out and the objects were already a little further out but could see the 3 in a triangle form and the lights. Thought if those were planes I would see them anymore. After watching them for about 45 minutes I came back inside, they were still in the same spot.
