Joe;

While all posters present good ideas and information, the fact remains that a hydraulic pressure sensing switch (while a VW switch may be cheaper and simple to install, and more reliable) will light those brakelights A LOT LATER than a mechanical switch sensing the pedal (figure it out...those 10mS at 60mph probably calculated out to a hundred feet traveled, and wouldn't you rather give the guy following you those hundred feet?)....as far as I'm concerned, I want to give the guy behind me ABSOLUTELY AS MUCH ADVANCE NOTICE AS POSSIBLE (need I remind you of your close calls?)!

And yes, developing the upgrade might be more of a challenge (than on 122s or 1800s) because of most of the linkage being under the floor, but motorcycles have effectively used actuating rods and switches LOCATED OUTSIDE, FOREVER!... I'm sure we could learn from them...maybe even use one of their (weatherproof) sealed switches.

People can always come up with lots of reasons why NOT to do something. I'm glad the Wright brothers, and a million other inventors out there, didn't, and don't, listen to them and quit!

Thanks also to Charles for the recommendation!

Cheers
