I have had DOT5 in TS30766 from day one in Sept 2008 and never a problem
with the brake light switch.  I think it is the one that came with the car
when I got it, pre-resto, in 2006.

The brake light switch failure rate is way too high.  I loose one as often
as you do and have been using DOT5 for about 25 years now (Gee 
that long??).  I replaced one just yesterday.   I keep a spare and a 
7/8th wrench in the boot.

I always thought it failed from the heat as my brake light switch is mounted
about 2 inches from the exhaust down pipe.  Next time the engine comes out I
intend to relocate the brake light switch towards the front of the engine
bay away from the exhaust system.
