at around 5 am this last week (can give exact day if needed), (it was rainy and dark). at the Greenfield and Pecos intersection, north bound, i was waiting to turn left/west onto pecos. i was in the right of the two left turning lanes. the arrow went through two cylces and never turned green for me. I ended up having to get through the intersection another way. appears to be a malfunction. I had this happen to me several months ago, always in the early hours.
