Okay, I've had to do a bit of a workaround.
Apparently, these lighted signs are running at a xxx-hertz whereby a smartphone camera can't capture the text that's displayed.
If you look at the actual photo, it's highly pixelated.
Anyway, so posting the photo, then what's written using a screenshot from Houston TranStar website ... and then I went overboard and posted a video that shows it's also pixelated doing a video capture
