Triadic,
Have you been to Launy in the dark? I don't care how good the a/c lights are mate, LT is " the black hole of calcutta" at night. Blind Freddy would know the lights weren't on(if this was actually the case) down there.
Just MHO but basic airmanship would dictate that the PAL/PCL would be activated or cycled before calling Centre for IFR traffic and taxiing.
