Get your reverse lamps signaling correctly again with the Beck/Arnley Back Up Light Switch 201-1826 (also written 2011826). This switch closes the reverse-lamp circuit when the transmission is shifted into reverse, telling the back-up lights to illuminate. It's a direct replacement for a wide range of BMW models, including the 2008-2013 128i, 2008-2013 135i, 2013-2018 320i, 1996-2000 and 2007-2016 328i, 2007-2015 335i, 2001-2007 525i, 2006-2012 550i, 2004-2010 X3, and the 2005-2012 MINI COOPER — see the "Vehicles it fits" section for the full 66-application list.
- OE form, fit and function: matches the original switch so it goes in as a direct replacement.
- Made-to-fit connection: built for the OE wiring harness and plugs.
- Premium materials: selected for corrosion resistance.
- High-quality construction: for durability, and application specific for these vehicles.
If a faulty back-up light switch is the reason your reverse lamps stay dark (or stay on), replacing it with this unit addresses that circuit. Diagnose the cause before ordering to confirm the switch, not the bulbs or wiring, is at fault.

Reverse lights that don't come on when you shift into reverse, or lights that stay on, can point to a failed switch. Confirm the bulbs, fuse, and wiring are good before replacing it.
