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.

The bulbs are bad, and I don't recommend using them. Use LEDs instead. it's not a hardware issue, the bulbs simply have a low runtime and they break easily.
