Changing brake light function

^Nope, some US owners have added a rear fog though. Most bought the physical housing that you cut the rear bumper for, but some wired up one of the inside trunk lights to be bright all the time.

 

Surprising is not obligatory on us roads when you see how safety this can be. On high density fog a rear fog light is so useful and crucial in my opinion and make a world difference in sight. I've been surprised more than once from cars in deep fog that didn't light up their fog light. I would never use a car without a rear fog light and especially on my 6th gen because i like and care of her ass so much

 

As far as I know here in Las Vegas they're not required.

 

its not mandatory in North America, some European & German vehicles do have them but not for Honda's.
