Keep your reverse lamps signaling correctly with the Standard Ignition Back-Up Light Switch LS-349. This switch detects when reverse gear is selected and closes the circuit, sending power to the back-up lamps so the lights behind you come on. It fits a wide range of BMW cars, including the 1992 325i and 325is, the 2007-2016 328i, the 2011-2013 335i, the 2006-2013 550i, the 1995-1999, 2001-2006, 2008-2013 and 2015-2018 M3, and the 2009-2013 Z4 — see the "Vehicles it fits" section for the full list of applications.
If a failed back-up light switch is the cause of back-up lamps that stay dark in reverse or won't turn off, this replaces it. Diagnose the cause before replacing. Color/finish: black and silver, metal and plastic. Country of origin: Spain.
