What are Brake Lights?
Before we dive into the wiring diagram, it’s important to understand the role of brake lights. Essentially, these are the red lights that come on when you apply the brakes in your truck. They’re designed to let other drivers know that you’re slowing down or stopping, so they can react accordingly.
