I once had an ACTO stating that I needed lights on the runway when arriving after sunset (in twillight), which is correct, but not a requirement if ATC was not established.
Depends on your definition of twilight
. The ICAO standard is clear ; You need runway light at night . Night is defined as Sunset + 30 minutes in the Northern hemisphere . so , no , in theory you do not need lights between Sunset and 30 min after
