ABSTRACT:
A visual monitor including a single light indicator for HID lamps (not needing a starter) and a visual monitor including two light indicators for an HID lamp, such as a high pressure sodium lamp, operating in conjunction with the starter. When the lamp is out, the presence or non-presence of an ignited first light indicator indicates lamp failure or ballast failure, respectively. The blinking or nonblinking of the second light indicator indicates whether or not the starter is producing satisfactory starting pulses.
