I have a ford focus titanium 1.6, my little problem is have the brake light on, all the time. This then knock the demister out-rear. Also the temperature is missing and lights come on for airbags and seatbelts.

sounds like a faulty speedo console (which has a load of other stuff in it including the main microchip that controls most of the electrics).  They can be dismantled and resoldered. There are companies that can recondition it for you - they take it apart and resolder parts of the circuit board where the solder has cracked / broken.

Solder on circuit boards in all electronics these days has a problem with brittleness / cracking due the regulations stopping the use of lead in solder.  Military / space craft etc have exemption and can still use leaded solder - because they know that any substitute is unreliable
