Now it seems that you guys are the 'fountain of all knowledge ' when it comes to cars , so what do you think about this please.
I have a Ford Ka (2004) and it keeps blowing both dipped beam bulbs, both are seperatly fused so it's not that, none of the other bulbs, main beam, number plate lights are affected, so I don't think it can be the alternator or voltage regulator, I have inspected the contacts of the switch and they appear ok, so I am a bit stuck.
So has anyone any idea please, .
Thanks in advance.
 
Several mid 2000's Ford models including mine had a problem with uncontrolled voltage spikes blowing bulbs, often caused when switching off high amp items like the rear screen or fans switching out. Headlights tend to go rather than other bulbs as they are obviously drawing far more current.

Ford issued a dealer bulletin and a fix involving a plug-in resistor wire that was then fitted to later models. It cured my cars problem so may be worth contacting Ford to see if yours was affected. Even if not, a resistor wire like that would protect from spikes which is the most likely cause after a bad connection on any car.
 
Thanks for your replys , just going to waggle the earth connections, then probably off to Ford.
You see I knew someone would have an answer.
