If you're looking to turn off the orange lights on your Kia K5, there are a few things you'll need to do. First, locate the fuse box. Once you've found it, open the lid and find the fuse labeled Taillights. Using a pair of pliers, remove this fuse and set it aside. Next, locate the taillight relay. It will be located next to the fuse box. Again, using a pair of pliers, remove this relay and set it aside. Finally, locate the wire that runs from the taillight to the body of the car. Cut this wire with a pair of scissors or a knife. With that done, your Kia K5's taillights should no longer be illuminated when you turn them on.
