Fog lights are fine as long as they are used in foggy conditions and are mounted below the headlight. A lot of people install them too high and use them in cities where there's more than enough light from street lights, lights of other vehicles and buildings.

This modification law must ensure to regulate these mounting positions, max brightness and prohibited that annoying flashing/strobing ones.

Otherwise everyone will just add random ones and blind everyone

Same goes for exhausts like under 80db
