I've never found that a problem. Admittedly, turning onto the runway with traffic waiting at the reciprocal hold point, I normally do turn the lights off as a courtesy. However, if crews leave them on whilst pointing at me, I just don't look down the centre of the beam. Never been an issue for me.
It happens a lot at places like HK with holding points on opposite sides of the runway, very annoying and inconsiderate to blast your landing lights straight into another crews face 100’ away.........
Anyway thread drift.....
