ATC blade fuses are used to protect a car’s electrical system including the vehicle's lights, engine, air conditioner, heat, wipers, and more. They are the standard for most modern automobiles, vans and light trucks. All of our fuses are color coded and have the amp rating stamped on the front to make them easy to identify. The transparent housing also lets you see when the fuse is blown, allowing you to quickly identify which fuse needs to be replaced.
