The rear fog lights are meant to turn on when there is a very heavy rain or foggy weather and that's why it needs to be bright so that the cars behind can see you under heavy rain, other than that I see nothing else is wrong with it... Hope my explanation helps you... Some people misuse it by turning it on when the weather is good, that's when it's annoying to the cars behind
