Help your brake lights respond every time the pedal goes down with the Standard Ignition switch SLS566, a stoplight (brake light) switch built as a direct-fit OE replacement. It fits many vehicles, among them the 2014-2017 Toyota Sienna, 2013-2018 Toyota Avalon and 2021 Toyota Yaris. See the Buyer's Guide tab for the full list and engine details.

The brake light switch signals the stoplights when the brake pedal is applied. If a worn or failed switch is why your brake lights stay on, flicker, or don't light at all, SLS566 replaces it. Diagnose the cause first, because bulbs, fuses and wiring can produce the same signs.

  • Direct-fit OE replacement: Designed for proper fit, form and function, and intended to return the stoplight switch to normal operation.
  • Copper alloy conductors: Chosen for electrical conductivity with low resistive losses.
  • 100% tested: Every unit is checked for both mechanical and electrical switching performance.
  • Controlled production: As a global manufacturer, Standard Ignition oversees quality control across the entire manufacturing process.
