Quick fix tire question??

Not any more. Bimetallic strips used to be used years and years ago before we had electronics... Nowdays, there is a simple ossillator circuit that produces a current every second or so that drives a relay(mechanical switch). The current to the indicator passes through this and is thus controlled on and off when the relay switches. Modern cars have extra electronics to communicate directly with the ECU so that there is continuous monitoring of the indicator and the status of the car..
