Original BMW Headlight and Fog Light Switch Unit for BMW E46 3 Series and M3 (1999–2006)

Mounted in the dashboard to the left of the steering wheel, this Original BMW switch unit operates the headlights and fog lights on BMW E46 3 Series and M3 models from 1999–2006. BMW's parts data calls it the switch unit for lights and fog lamps, and it is made in Germany. A headlight switch is the driver's control for the exterior lighting, including the headlights and running lights, so a faulty one can leave the driver's vision impaired in the dark. It is sold as one complete switch unit.

Original BMW Parts carry a 24-month parts warranty.

BMW built E46 light switches in more than one version, and this unit is the one for cars with halogen headlights and fog lights. It is not meant for cars equipped with automatic headlights, so check whether your car has them before ordering. Because fog lamp control is part of the same unit, cars without factory fog lights fall outside what this switch is made for. BMW started production of this number in December 2006.

Common Questions

My headlights will not turn on. Could the switch be at fault?
It can be. A faulty headlight switch is one reason the headlights stop working, and these switches fail from wear and tear, wiring issues, and exposure to the elements such as rain, snow, or heat.

Can this switch go into an E46 built before December 2006?
Yes. BMW rates this number as exchangeable retrospectively, so it takes the place of the earlier switch on cars built before it went into production.
