Get your reverse lights working again with the Standard Ignition Back Up Light Switch SLS-381 (also SLS381). This switch senses when the transmission is shifted into reverse and completes the electrical circuit that powers the vehicle's back-up lamps. It installs as a direct-fit replacement for the 2002 Suzuki Aerio.

  • Function: Detects reverse-gear engagement and closes the circuit to activate the rear back-up lights.
  • Direct-fit application: Cataloged for the 2002 Suzuki Aerio.
  • Straightforward swap: Replaces a worn or failed original back-up light switch.

Signs the original switch may need replacing include back-up lights that fail to illuminate when you select reverse, or lights that stay on. Because these symptoms can have other causes, diagnose the circuit before replacing; if a failed back-up light switch is the cause, this replaces it.
