Hydraulic Brake Light Switch | 1966 Bronco, 39-66 Ford Truck SKU: 6079

Hydraulic Brake Light Switch | 1966 Ford Bronco, 1939-66 Ford Truck

Maintain safety and originality on your first-year Bronco with this Hydraulic Brake Light Switch, designed for the 1966 Ford Bronco and 1939-66 Ford Truck. This switch is a vital component of the brake system—it activates your brake lights by sensing hydraulic pressure when the pedal is pressed, ensuring following traffic sees you stop.

Threading directly into the factory single-reservoir master cylinder, this switch delivers reliable performance and hassle-free installation for restoration or maintenance. Unlike later models (1967–77 Bronco), which moved the brake light switch to a mechanical setup at the pedal, the 1966 Bronco used this hydraulic design—making this part year-specific and essential for an accurate build.

• Year-Specific Design: Correct part for 1966 Ford Bronco or 1939-66 Ford Truck with single-reservoir master cylinder.

• Pressure-Activated: Triggers brake lights when hydraulic pressure builds during braking.

• Direct Fit: Threads into front port of factory master cylinder—no mods required.

• Reliable Function: Restores proper brake light operation for safety and road readiness.

• Restoration Correct: Matches the original switch type used only in 1966 Broncos.

• Not for Later Models: 1967–77 Broncos used a pedal-mounted mechanical switch with dual-reservoir master cylinders.
