I can't fully agree with that, Howard. Yes, the special 55/56 switch seems to fail with silicone fluid quite quickly. But I know of plenty of pre-55 Packards with silicone fluid that have had a functioning hydraulic brake light switch for 20 years or more, some much more. Sure, there may be the occasional switch that fails prematurely, but in my experience that's very, very rare.
