Depends whether you drive at a sensible speed or fast! With (the lights as the manufacturer set them) cars approaching it was like having no lights at all when they were dipped - To avoid danger to those approaching I didn't try them on beam
Modern cars have more refined distance adjustment, usually via a little wheel thingy, to allow you to adjust the pitch of the dipped lights. When I first used the dipped headlights on our Auris on a dark lane it was set very close, but turning the little wheel on the dash set it much further down the road so that even without resorting to full beam I could see well ahead. The idea of that adjuster is that if you put a lot of heavy stuff in the boot the back of the car can drop a little and the angle of the beam can rise too high, so you adjust it down to avoid dazzle. But then when you next use the car in the dark with nothing in the boot the beam is aimed too low so you adjust it up.
Yes - I'm well aware of that as I used to work in car design/development. As the car was provided to us, with the 'passengers on board adjuster' adjusted to put the beams as their highest, the light were still pointing 'at the ground'
MOT stations should be checking/adjusting the beams with the adjuster set to its highest beam position, otherwise approaching cars may be dazzled if the driver adjusts it to a higher beam setting. The adjustment is there to enable the driver to adjust the beam lower
when there is more luggage/passengers on board, as stated by a previous poster. It should never be possible (without putting weight in the car
) to adjust the beam higher than the regulated position.
