Headlight Switch Options

December 14, 1999
By: Robert Leidy


For most, the stock headlight switch has a black cap (61-31-8-400-003) on top of a black sleeve (61-31-8-389-547). Some Z3 were ordered with a chrome package installed at the factory and might have a different all chrome switch but this is how the majority of Z3s rolled off the assembly line between 1995 an 1999. The cap simply snaps onto the sleeve, the sleeve is screwed on and held in place with an 8mm nut. Both can be replaced in a couple minutes.

If you just wanted to replace the cap you could order BMW part number (61-31-8-400-004) which is an all chrome cap. This is a very eye catching combination but some think that the all chrome cap is a little too eye catching. The chrome cap lists for $6.83 and it simply snaps on in place of the black cap. Be careful snapping the new cap in place, there are three pins that line up into some slots so make sure those line up before trying to snap on the cap.

If you wanted something a little less flashy, BMW also offers a chrome trimmed black cap. BMW part number (61-31-2-694-602) lists for $10.20 and it also just snaps on in place of the black cap. This cap is trimmed in chrome with the face remaining flat black. This is the same cap that is now standard on the model year 2000 M roadsters.

If you are wanting even more chrome, the sleeve behind the snap on cap also comes in a chrome version. BMW part number (61-31-8-389-880) lists for $6.40 and once the cap is removed a single 8mm nut can be seen that holds the sleeve in place. The sleeve also has metal threads so once the nut is removed the sleeve has to be unscrewed and replaced.

Z3s that were ordered from the factory with the chrome package received a chrome cap (61-31-8-400-004) on a chrome sleeve (61-31-8-389-880). The total list cost of the two parts is $13.23

What I choose to install in my M roadster is the combination of a black chrome trimmed cap (61-31-2-694-602) on the chrome sleeve (61-31-8-389-880). The total list cost of the two parts is $16.60 and it blends well with my ever growing chrome collection.

Not pictured, but also available is an Aluminum cap (61-31-8-401-196) and an Aluminum sleeve (61-31-8-401-270). These were offered as part of an Aluminum package on the now discontinued 2.8 coupe.
