ya ive checked those too and the rear day lights and the front daylights and all the interior lights as well..still the light only goes on when the switch is turned on...if a light outside of that circuit goes out,for example a brake light or a signal light..the "light out" light will function normally....could there be a problem with my rear tailight...the one where the electrician grounded to the body instead of running it to through the wires up to the board/computer??
