Brake light Switch replacement

For SLK 230 R170 chassis

Brake light switch was faulty causing back lights to burn out and weld to chassis. I saw another link on this with diagrams. Thought these color pics would make it a bit easier.

You will be replacing this:

You can buy it here.

DETACH NEGATIVE CABLE from BATTERY TERMINAL. Using 10mm socket. Wait 2-5 mins.

Step 1. Remove lower panels as described here:

Step 2. Locate brake light switch near brake pedal.

Step 3.
Detach the two wires from brake light switch (note where they were attached.)

Step 4. Press clip on brake light switch and twist out of bracket. I demonstrate motion for removal in this
. (For my fellow visual learners)

This is the metal bracket without the brake light switch. You will install the new switch back into this bracket.

Installation is reverse of removal.
