If the street light in front of your house or on your street is not working, call SRP at:
602-236-5555
You'll be asked for the street light number (pasted on the light pole), and the location. The main cross streets and the closest address, if possible. Also, leave your name and number and someone should get back to you about when they will be out to fix the problem.
You may have to call a few times to get results.
Have a neighbor call, too. (Squeeky wheel theory)
