There was a time when car sidelights were not very bright but adequate: headlights dazzled on full beam and but not when dipped. Lower lights were classed as fog lights and usually pointed to the near side of the road and were only allowed in appropriate weather conditions. Today we have side lights that are as bright as head lights but are not dipped: head lamps when dipped which are as dazzling as old headlamps on full beam: cars with side lights, head lamps and lower lights all of which appear to be on full beam. I have to dip my mirrors whenever cars are on my tail to stop being dazzled from both directions. Manufacturers are obviously allowed to provide these lamps but I wonder has the law been changed or has it not caught up with the latest lamp technology? If this is of general interest, feel free to edit my ramblings.
