Tech Insight
Unlike mechanical brake light switches that rely on pedal movement, a hydraulic pressure switch activates based on actual brake line pressure. This ensures your brake lights come on exactly when braking force is applied—especially useful in custom pedal setups where traditional switches can be inconsistent.
Using a -3 AN inline union with an NPT port keeps the install clean and serviceable. It allows you to integrate brake light functionality without adding brackets or complicated linkage setups, making it a go-to solution for clean, reliable wiring on custom builds.
