Help your brake lights signal each stop with the Standard Ignition switch SLS-138, a brake light switch (listed by the manufacturer as a stoplight switch). It is a direct-fit replacement for the listed applications and fits many vehicles, among them the 1977-1984 Subaru DL, the 1979-1984 Subaru GL and the 1989 Subaru GL-10; see the "Vehicles it fits" section for the full list and engine details. The switch closes the brake lamp circuit when the brakes are applied, which signals drivers behind you that you are slowing or stopping.
Brake lights that stay on, won't light, or work only intermittently are signs this part may need replacing. Bulbs, fuses and wiring can cause the same symptoms, so diagnose the circuit first. If you are shopping for a GL switch, this unit is also listed for the 1979-1984 and 1986-1989 Subaru GL.
