**Update**

Started my roadster today for the first time since I noticed the low tire pressure light last December. It did not come back on this time, so it obviously reset itself during the time the car was sitting in the garage. I figured it would not reset until I drove the car but that is not the case.

I still can't figure out how these things work, but they do. Bugs the hell out of me trying to figure out the operation of these but I need to move on.

Again, thanx for everyone's input. Happy Motoring all.
