well the point is not that they will blind anyone, but that they will make it looke like you are braking because they are brighter than the bulbs next to them when you put your lights on, so people may mistake you for braking when you really are not.
i never really put that light on (well i did once) so no worries with the cops.
and Jim, you know how some idiot is always behind with his/her brights on and on a cellphone, flashing those might upset her/him and they will wanna blind you with their high beams, they will go to turn them on and figure out that they are already on and turn them off hopefully (just a theory
)
