There are several ways to report a broken street light. You can click on the Edison link here, Southern California Edison which will direct you to Edison's Online Request Form's page. On this page you will notice a link to their Report Street Light Outage form. Fill in the requested information and Edison will notify you when the work is completed.
If you prefer to call Edison directly, please contact them at (800) 655-4555. The automated phone system's prompts will have you press 1 ("power outages"); 3 ("anything else") and finally 3 ("street light needs repair") which will then transfer you to an Edison representative.
The final way to report a broken street light is to please contact the Public Works department directly at (909) 394-6240, or via email: email@example.com.
