Re: D.O.T. 3-4 vs. D.O.T. 5 for a '56 Patrician

Tim, not sure if you missed this or not, but the relationship between hydraulic brake light switch failure and DOT 5 is almost exclusively associated with the unique switch used on the 55/56 cars with TL - preponderance of evidence on this (only) switch and DOT 5 is extensive. In my experience there is no supportable finger-pointing with regard to other brake light switches failing prematurely with DOT 5.
