What’s in it

This bill prohibits a motor vehicle from being equipped with headlamps or auxiliary driving lamps that display light that is a color other than white. A person who violates Code section 321.385 or 321.403 commits a simple misdemeanor punishable by a $45 scheduled fine. The bill does not affect the color requirements for signal lamps under Code sections 321.317 and 321.404.
