You are correct there are replacement bulbs that can be fitted into existing headlights, mainly in older cars, many are illegal and should not be available in the UK. They should get picked up on the MOT
At 75 my eyes are normal, driving home on Sunday I took particular notice it was very busy only 2 cars were abnormally bright.
PS when I’m old and my eyes are bad, the wife can drive.
