Kind of? It is with overly bright tail lights. The standard for how bright a light should be is stated in watts. That was fine for incandescent lights but watt is a description of power, not brightness. So when more efficient led lights came out they still needed to be a certain wattage and are too bright for purpose. Example my led lights in the house are 850 luminaries. They are approx equivalent to a 40w bulb. They only draw 8 watts.
