This little guy basically does exactly what it sounds like – it turns your brake lights on when you press the brake pedal. It's a simple on – off switch triggered by the mechanical movement of the pedal. Modern ones are often adjustable, letting you fine – tune how much the lights activate. Some also integrate with things like cruise control, telling the system when you’ve hit the brakes and it needs to disengage. It’s part of the electrical system, naturally, and lives up near the brake pedal, usually mounted on the bracket. When you push the pedal, it physically closes a circuit, sending power to the brake lights. It's a pretty straightforward setup, but a critical one. It also often communicates with the vehicle’s computer to confirm brake application. Well, beyond just being legally required for safety – letting drivers behind you know you’re slowing down – it’s a really important safety feature. If it fails, your brake lights won't illuminate when you press the pedal, hugely increasing your risk of being rear – ended. You’ll notice if it's gone bad usually because your brake lights stay on all the time, or worse, don't come on at all. It acts like a shield, letting other drivers react to your actions. We have a good selection of these on Fixparts Online if you're looking to replace it yourself, and they aren't too difficult to change on most vehicles.
