I have some questions about indicator lights on the 757 (and/or 67)
1) Does BATT BUS power ALL indicator lights (except Batt OFF and right Utility Off), or there are some powered by other buses? (for example, Fuel Pumps OFF lights, or Hyd Pumps OFF lights, Window Heat Off Lights, etc)
2) In case other buses do power indicator lights, which ones are powered by which buses?
3) Each time a generator (Left/Right/APU or ExtPwr) comes on line, CRTs and instrument lights tied to Main AC buses blink for some milliseconds. Do indicator lights blink as well, even if not tied to main AC buses?
