Does anything wierd happen like lights lighting dimly when you open the door?

It turned out that the bulbs in the headlights had gone simultaneously. Luckily my son is knowledgeable about cars. He came over and figured out the problem. I had to purchase new bulbs, then my son had to practically dismantle the front of the car to change the bulbs. It was a complicated operation just to replace bulbs, and something I would not have been able to tackle myself. If it had not been for my son. I would have had to spend a fortune at a garage for a mechanic to replace the bulbs for me. What should have been a relatively simple task has become a mammoth operation. In years gone by it would have been a simple task that I could have performed myself. Why do manufacturers design cars so that it is so complicated just to replace the bulbs. There are so many things that have developed faults on this Ford Focus, I will never have another one.

my advise don't get those, they don't work as well as you think they do.
if you think about it if they are so much better why don't drag racers use them?
because they actually block the ignition point.
just get the factory style plugs and you will be better off.
