What are the lighting laws in my state?

Most car enthusiasts like yourself love to hear people give you props for all the work you've done to your vehicle if it's from a new high horsepower motor or to a set of custom-made lighted mud flaps with your own personal saying that lights up at the flip of a switch.

Even though we love to trick out our rides there are laws we should be aware of. Each state is a little different on what color lights they allow and what is not allowed, and how it is allowed to be installed on a vehicle. So many rules right! But don't worry we have all 50 states lighting laws. If you choose to install aftermarket lighting of any sort on your vehicle, just take a little precaution.

If you are ever pulled over for lighting on your vehicle, be sure to carry a copy of the lighting laws with you in your vehicle. And present it to the officer if you are pulled over for lighting issues. Respect the police officer as they are the ones to come to your aid if your house is being broken into, or if you are being shot at. Show them the respect that they deserve and they should respect you just the same.

Our recommendation is, if you want lights for your car, get them and enjoy them, but If you end up getting a lot of hassle just flip the switch off for public roads and save it for off-road and car shows.

They can't hassle you if they can't catch you........
