Standard Ignition Brake Light Switch P/N:SLS-346
Standard Motor Products
Help drivers behind you see when you slow or stop with the Standard Ignition Brake Light Switch / Stoplight Switch SLS-34, the switch that turns the brake lights on when the brakes are applied. It fits many vehicles, among them the 1980-1984 Volkswagen Jetta, 1985-1989 Volkswagen Transporter and 1965-1970 Ford Cortina, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list. Standard Ignition catalogs this part as a stoplight switch, and it is also known as a brake light switch.
Signs this switch may need replacing include brake lights that stay on, brake lights that do not come on when the pedal is pressed, or brake lights that work only intermittently. If a failed stoplight switch is the cause, this unit replaces it. Bulbs, fuses and wiring can cause the same symptoms, so diagnose the circuit before replacing the switch.
