I found the following website post dealing with the untimely death of many pressure operated brake light switches. Many are under the impression DOT 5 fluid is the culprit. The switch I installed in 2019, a Harley Davidson switch failed last week. No continuity. The link below takes you to a fella who cut the failed switches open to determine what failed. He contends it has little to do with fluid type as the failure occurs in the dry side of the switch. He says the contacts burn because with hydraulic activation the contacts are brought together slowly, the incandescent load is high and there is no wiping or self-cleaning action of the switch contacts. He says Volvo gave up on them along with every other mfg after 1967. I have one in a 63 Ford that failed after 19 years of DOT 3. I have an original, never been out, on a 1960 Buick on DOT 3. Options are to replace the switch and see if it will go 4 years like the last one, use LED bulbs, install a relay, or install a mechanical switch on the pedal arm as many of you have done. https://www.sw-em.com/hydraulic%20brake%20light%20switches%20notes.htm
