You've got that backwards: I wrote that rude and nasty lights are unapproved lights. I acknowledged that there are some OK unapproved lights, but how else can you tell which, short of testing them yourself? Lots of cyclists seem keen to recommend nasty dazzlers.
Good grief have you seen MTB lights?
£500+ in lighting to turn night trails into day time with bike, chest and head mounted lights!
Yes, you would see them coming the other way as you veered into a crowded bus stop full of children...
