Keep your reverse lamps responding the moment you shift into gear with the Standard Ignition Back Up Light Switch LS-309. It's a direct-fit replacement for the 1988-1994 Subaru Justy (see the Buyer's Guide tab for engine-level applications). This switch senses when reverse gear is selected and completes the circuit that powers the back-up lights, so the vehicle behind you sees when you're backing up.

  • Copper alloy conductors: deliver strong electrical conductivity with low resistive losses.
  • 100% tested: each switch is verified for both mechanical and electrical switching performance.
  • Robust design, high-grade materials: built to meet the demands of today's service professionals.
  • OE-focused engineering: from a global manufacturer of original-equipment ignition products with quality control across the manufacturing process.

Signs this switch may need replacing include reverse lights that stay dark when you shift into reverse, or lights that stay on or flicker. Because these symptoms can have other causes (bulbs, wiring, or fuses), diagnose the circuit first; if a failed back-up light switch is the cause, this replaces it.

Frequently Asked Questions

What does this back-up light switch do?

It senses when the transmission is shifted into reverse and completes the circuit that powers the vehicle's back-up (reverse) lights.

What vehicle does the LS-309 fit?

It's a direct-fit replacement for the 1988-1994 Subaru Justy. Check the Buyer's Guide tab to confirm the application for your vehicle.

What are signs this switch may need replacing?

Reverse lights that fail to come on when you shift into reverse, or lights that stay on or flicker, can indicate a faulty switch. Diagnose the circuit before replacing.

What is the switch made of?

It uses copper alloy conductors for strong electrical conductivity with low resistive losses, along with robust, high-grade materials.

Is this switch tested before shipping?

Yes. Standard Ignition states each switch is 100% tested to verify both mechanical and electrical switching performance.
