Beck/Arnley Brake Light Switch P/N:201-1821
Keep your brake lights signaling and your pedal-activated systems responding with the Beck/Arnley Brake Light Switch (MPN 201-2397, also written 2012397). Mounted at the brake pedal, this switch closes the circuit when you press the pedal to illuminate the brake lights and send the brake-applied signal used by systems like cruise control and the shift interlock. It's a direct-fit replacement for a wide range of Lexus and Toyota applications, including the 2006 Lexus GS300, 2007-2011 GS350, 2001-2006 LS430, 2008-2013 IS250 and IS350, 2002-2010 SC430, and the 2008-2009 Toyota Prius — see the Buyer's Guide tab for the full list.
Signs the original switch may need replacing include brake lights that stay off or stay on, cruise control that won't engage, or a shift interlock that won't release. If a failed brake light switch is the cause, this replaces it. Interchange: 1S5791 · SL2087 · 8434030110 · SLS347 · JA4419
