Signal device troubleshoots common fixture problems
I.Q. On Board troubleshooting LED signal device provides at-a-glance diagnostic information for outdoor light fixtures. Available as retrofit attachment to companion lighting fixtures or standard on new fixtures. Connects directly to fixture ballast compartments. Problems can be spotted from pedestrian or vehicle levels. When a lamp does not go on, a LED will light (steady or blinking) if the failure is due to the lamp; if the LED does not go on, a ballast failure has occurred.
