Last post about this,

I looked up the bill where the Mercedes dealer replaced the '"Stop light Switch" 15 months ago. it lasted a little over 13,000 miles, but that's not good enough.
I put that thought about solving the problem back in the drawer because the switch was installed new less than two years ago.

My point being, don't trust what was recently done to still be in working order.

I hope my problem and solution could help another.
