Describe the bug

Not a bug but a question. After the merge of #7177, the pack fault lights illuminate when the pack flow valve disagrees with commanded position. This includes when the aircraft is powered up before bleed air is available.

When the power is supplied by the batteries (external power not connected), only pack 2 FAULT light illuminates. This is not consistent with some of the videos I've seen online but might be specific to this aircraft. I believe this comes from the fact that each pack light pushbutton is powered by a different electrical bus (ref #3980). Is this the correct behaviour?

Expected behavior

Either both FAULT lights should illuminate, or none.

Steps to reproduce

1. Spawn in C&D
2. Turn on batteries (not external power)
3. Observe the pack fault lights on the overhead panel

... Note the same invalid behavior is when the pack is switched off. For PACK 2, white OFF label appears. However, for PACK 1, even when switched off, no white illumination appears.

Checked on an A21N should be the same as A20N, pack 1 fault light lights up while powered by batteries only
