You do realize that you've made my point, don't you? You missed the important part of the above definition...to cause physical damage...; to injure. Where is the physical damage or injury? You might have a blue spot of you looked into the light from a few inches away (hardly something that is going to happen in a car/bike interaction) but that isn't an injury. Nor is it really all the painful unless you put the light almost on your eye. It may be slightly uncomfortable to look at a bright light but hardly painful or injurious.

And a motorist is going to have interactions with lights that are much brighter and much closer than most bike lights are going to be all the time. If those lights aren't causing injury or physical damage or pain, how is a bike light...which is usually of a much lower intensity...going to cause any worse pain?


Perhaps you should follow your own advice. Your own narrow definition of the word is equally wrong. Mild discomfort isn't damage or injury or, for that matter, even real pain.
