Most recent update, green housing, 4-pin brake light switch for A4 chassis MkIV Jetta, Golf and New Beetle. Also fits the MK7 Golf and Golf Sportwagen.
The new GREEN version of this switch is MUCH easier to install than the previous editions were. There is not adjuster or lock that needs to be set, and it can be taken out and installed multiple times (rather than being a one-shot install).
