Dorman Stoplight Switch Assembly Compatible with Select Ford/Lincoln/Mercury — Direct-Fit, OEM-Style Connector

The Dorman 926-487 stoplight switch assembly is a direct-fit replacement designed to restore brake-light and electrical switch function on compatible Ford, Lincoln, and Mercury vehicles.

If the brake lights, cruise control disengagement, or other brake-switched systems in your vehicle are acting intermittently or not responding, a failed stoplight switch is a common cause. The Dorman 926-487 offers an aftermarket replacement that matches the original equipment’s fit and basic operation for the applications it supports, helping you regain reliable switch performance without modifying the vehicle wiring or mounting.

Which vehicles does this stoplight switch fit?

This assembly is manufactured to replace the original switch on specific Ford, Lincoln, and Mercury models—always confirm fit with your vehicle’s make, model, year, and trim before purchasing. Dorman provides a garage-tool lookup so you can verify compatibility for your VIN or vehicle configuration.

• Designed for select Ford, Lincoln and Mercury applications (check vehicle selection tool).
• Forms and connector style match the original switch on supported models.

How does installing this switch affect my vehicle’s systems?

The stoplight switch is a small but critical electrical component: it signals when the brake pedal is pressed and impacts brake lights, cruise-control release, and other brake-dependent circuits. Installing a properly fitting replacement returns correct signalling to those systems when the original switch has failed.

• Restores brake-light activation and timing to the original behavior.
• Re-enables brake-switch dependent electronics such as cruise control disengage.
• Maintains OEM-style connector and mounting for straightforward replacement.

Installation is typically straightforward for anyone comfortable with basic automotive tasks: locate the factory switch at the brake pedal assembly, disconnect the electrical connector, remove the old switch, and install the replacement using the same mounting points. If you’re unsure, a professional technician can complete the swap quickly.

• Disconnect the vehicle battery or ensure ignition is off before starting.
• Access the brake pedal area, unplug the connector, and remove the original switch.
