Keep your brake lights signaling every time you hit the pedal with the Standard Ignition Brake Light Switch SLS-147. It's a direct-fit replacement for a broad range of classic Mopar applications, including the 1962-1969 Chrysler 300, 1961-1969 Chrysler Imperial, 1960-1972 Dodge Dart, 1970-1972 Dodge Challenger, 1966-1972 Dodge Charger, 1964-1972 Plymouth Barracuda, 1961-1972 Plymouth Valiant and many more — see the Buyer's Guide tab for the full 40-application list.

  • Core job: the switch senses brake-pedal input and completes the circuit that turns on the brake lights.
  • Signs it may need replacing: brake lights that stay dark when you press the pedal, stay on when you release it, or flicker intermittently — if a failed brake light switch is the cause, this replaces it.
  • Safety role: restoring proper switch operation helps signal following drivers when you brake.

Brake-light faults can also stem from bulbs, fuses, or wiring, so diagnose the cause before replacing. Because this is a switch that triggers off the brake pedal, install it per the vehicle service procedure.

Interchange: Manufacturer part number SLS-147 (also SLS147).

Frequently Asked Questions

What does the SLS-147 brake light switch do?

It senses brake-pedal input and completes the electrical circuit that turns on your brake lights. If a failed switch is the cause of non-working brake lights, this replaces it.

Which vehicles does this switch fit?

It's a direct-fit replacement for many classic Chrysler, Dodge, and Plymouth models, including the 1960-1972 Dodge Dart and 1961-1972 Plymouth Valiant. See the Buyer's Guide tab for the full 40-application list.

What are signs my brake light switch may need replacing?

Brake lights that stay off when you press the pedal, stay lit when you release it, or work intermittently can point to a failed switch. Confirm the cause before replacing.

Could something else cause my brake lights to fail?

Yes. Bulbs, fuses, wiring, and connectors can also cause brake-light problems, so diagnose the actual cause before assuming the switch is at fault.

How is this switch installed?

It's a switch triggered by the brake pedal. Install and adjust it following the vehicle's service procedure for correct operation.
