what would cause the reading lights up front to keep going out?

What is your question?

Had the A 4 for about a week, the lights went out. Took it in to Carmax (where we bought the car). They replaced the bulbs and 2 weeks later the lights went out again. Took it to Carmax, they sent the car to a Audi dealer and they said they couldn't find anything wrong, they replaced the bulbs and the lights lasted about about a month and they went out again.
