Yep, under the hood inside the brake booster bracket.

Open the hood, have a mate operate the brake pedal and you will see a part of the brake linkage press the little black button in and out in a perfect world.

Sometimes a little spray lubricant and judicious movement of the black plunger with a screwdriver will bring it back to life. (this message brought to you by Mike Self)

I battled with my brake lights just recently.

Do the following (try brakes after each attempt):

1-Check the fuses and clean the contacts.

2-Check that the 12v lead to the brake switch has power.

*If no voltage check the connections at the fuse box (below) clean them.

3-Check if the brake switch is working with a multimeter if not replace with new one.

*You can bridge the 2 cables to see if the lights come up.

4-Check the line from the output of the switch I think (green/red) may vary. To the LH rear brake lamp with a multimeter it must show continuity of the electrical current.

5-If none of this works check if your bases are worn out and the bulbs are loose if that's the case (like my car) then it's well... not nice.

Good luck!

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
