Question: What are the laws limiting the different color lights you can have on your tires or undercarriage of your car? Are under vehicle ground effect lights legal in Arizona?
Answer: There are many different extras you can add to your car to make it look really
cool, including several types of lights that attach to various places on your
car. Although these lights can make your car look cool, safety is one of the first
considerations for Arizona laws on this topic. There are very specific guidelines
in Arizona Law concerning colored lights and undercarriage or "Ground Effects"
Arizona law says (ARS §28-931) that any reflectors or lights mounted on
the front or front side of a car be "amber" which is a yellowish-orange
color. And any reflectors or lights on the back or side back must be red, except
for signal lights which must be red, yellow or amber. The light illuminating
the license plate must be white.
Arizona Law (ARS §28-940) also addresses other car and truck lighting
equipment. A car or truck cannot have:
- more than two side or fender lights and they must be amber or white color.
- more than one running board light on each side and they must be white or
- more than two backup lamps (like a spotlight) but the backup lamps must
not be shining while the vehicle is in motion.
Also, Arizona Law (ARS §28-947) has restrictions on the type of headlights
you can have, and their brightness. And it is against Arizona Law for any car
other than an emergency vehicle to have a red or blue light visible from the
front of the vehicle.
So, Arizona Law allows you to have certain lights of certain colors on your
car, but you cannot put differently colored lights on the body, under carriage
or tires of your car. Safety is the priority, and colored lights can be distracting.
People's eyes need to be on the road instead of looking at cool lights in order
to avoid causing accidents.
Don't forget that some lights on your car are mandatory, like break lights,
turn signals and headlights. You can be pulled over if any of these lights aren't
working properly, so make sure to do regular maintenance on you car.
