The reason for a certification, is to make it easier to buy a decent tail light, and easier for states/provinces to word laws requiring them. For example a state requirement for a tail light that meets federal certification, is easier then expecting one to know whether a specific unit is visible a certain distance back. It also makes buying one easier, in that you just look for models that meet that same certification.
