Keep your reverse lights responding the moment you shift into gear with the Beck/Arnley Back Up Light Switch 201-1788 (also written 2011788). Threaded into the transmission, this switch closes the circuit when the gear selector moves into reverse, sending power to the back-up lamps. It's an application-specific replacement for a long list of Lexus, Scion and Toyota models, including the 1990-1991 Lexus ES250, 2005-2016 Scion tC, 1989-2011 Toyota Camry, 1988-2010 Toyota Corolla, 1995-2015 Toyota Tacoma and 2007-2014 Toyota FJ Cruiser — see the Buyer's Guide tab for the full list and engine specifics.

  • OE-matched: built to match OE form, fit and function.
  • Correct connection: made-to-fit OE wiring harness and plugs.
  • Corrosion resistance: premium materials help resist corrosion.
  • Durable build: high-quality construction for durability.

If a failed switch is the cause of dark reverse lights, this is a direct-fit replacement designed for the listed applications. Diagnose the circuit before replacing to confirm the switch, rather than a bulb, fuse or wiring, is at fault.

Frequently Asked Questions

What does this back-up light switch do?

It closes the electrical circuit when the transmission is shifted into reverse, sending power to the back-up (reverse) lamps so they illuminate.

What are the signs this switch may need replacing?

Reverse lights that stay dark, work intermittently, or stay on can be signs of a failed switch. Diagnose the circuit first to rule out a bulb, fuse or wiring issue.

Will this fit my vehicle?

It's an application-specific replacement for many Lexus, Scion and Toyota models. Check the Buyer's Guide tab against your year, make, model and engine before ordering.

Where is this switch located?

It threads into the transmission, where it detects the reverse gear position. Refer to your vehicle service information for the exact location and installation steps.

Does it come with the connector or wiring?

The switch is made to fit the OE wiring harness and plugs. It is the switch itself; consult the service procedure for any additional components your vehicle may need.
