Hi Charlie, Just read your post and it sounds like your alternator is over charging and causing the bulbs to blow, this might do some other damage if left this way, can you get a hold of a volt meter and attatch it to the battery, it should show around 13-14 volts with the engine running and around 12-12.5 volts with ignition off. If the voltage is a lot higher than 14 volts then you should have the alternator swapped as the regulater has gone, hope this helps you save blowing any more bulbs !
