Two bright lights

Two bright lights
I just wanted to post this here in case anyone saw something similar or might know what this could have been. 
Time: about 7pm
Location: SW United States
I was walking into my house from my car. I looked up like I normally do and immediately spotted 2 stars that looked out of place and brighter than they should be. They were between Orion’s Belt and Rigel and a little brighter than any stars in that constellation. As I watched them for a few seconds and wondered if my phone still had enough battery to use the SkyGuide App, they started to fade, got bright for a second and then faded again and disappeared. They didn’t move at all just kind of dissolved away. I assume satellites or space debris would’ve been moving and I just can’t think of anything else with these characteristics. If anyone had seen something similar and knows what might cause that, let me know.
