Keep your stop lamps switching on the instant you hit the brake pedal with the Standard Ignition Brake Light Switch (P/N SLS-25). It completes the brake-light (stop-lamp) circuit when the brakes are applied, and it drops in as a direct-fit replacement across a wide range of vintage American vehicles — including the 1961-1962 Checker Marathon, 1937-1939 and 1949-1954 Chrysler Imperial, 1946-1948 DeSoto S-11, 1948-1950 Dodge B-1, 1950 Fargo FN1 Pickup, 1951 Henry J Deluxe, 1938 Hudson Terraplane, 1961-1968 International Scout, and 1959-1961 Jeep CJ5. With 137 applications listed, see the Buyer's Guide tab for the full list.
If a worn or failed brake light switch is behind your stop-lamp trouble, this unit replaces it; diagnose the circuit first, since bulbs, fuses, and wiring can produce the same symptoms.
