Still working perfectly. The crap Echlin part would begin to fail by requiring more and more pressure to light the brake lights. The Ron Francis part turns on with a lot less pedal pressure, and it hasn't seemed to increase.
It's $20, but in my opinion worth it. It's compatible with silicone fluid which I run in my Rambler (a waste as it turns out, but I'm not going through he hassle of switching back to DOT3).
