Is there a system variable that turns on/off the lightbar (white lights) when system is on? I have 3 Front Planes and 2 of them refuse to turn the white lights on after the system has finished the Diagnostic on startup. I have 5 lightbars that appear to have good bulbs, but swapping them out didnt help. The Red light comes on but no white lights afterwards.
