Original BMW Headlight and Fog Light Switch for BMW 1 Series, 3 Series, and X1 (2009–2015)

This Original BMW headlight switch unit is the dash-mounted light control that runs the headlights and fog lights on 2009–2015 BMW 1 Series, 3 Series, and X1 models equipped with fog lights and a rain sensor. BMW names the part the light control element, part number 61-31-9-169-398, and has produced it since September 2008. This version is specified for cars that carry both front fog lights and the rain sensor, so its control layout matches that equipment. The face has a pergranz chrome trim finish. Each switch is made in Romania and sold as a single piece.

Original BMW Parts carry a 24-month parts warranty.

One part number covers several chassis from the same period. It serves the E82 coupe and E88 convertible 1 Series, the facelifted E90 sedan and E91 wagon 3 Series, and the E84 X1. BMW's parts data matches it to a wide spread of engines: the N51 and N52N naturally aspirated sixes, the N54 and N55 turbocharged sixes, the M57N2 diesel in the 335d, and the N20 four-cylinder in the X1. A headlight switch is the driver's main input to the exterior lighting circuit, turning the low beams, parking lights, and fog lights on and off from the dashboard. Since the same unit spans three model lines, a shop servicing several of these cars can stock a single number.

Common Questions

Will this switch fit a car without fog lights?
BMW specifies this unit for vehicles that have both fog lights and a rain sensor. Confirm your car has that equipment before ordering.

Why do headlight switches fail?
Wear from daily use, wiring issues, and exposure to rain, snow, or heat are the usual causes. Headlights that will not turn on or behave erratically can point to a faulty switch.
