If an exterior lightbulb goes on your car, it may be a while before you notice it. Some cars do have a warning system that tells you that a bulb has gone, but not always where. Ideally you should always check your lights when going on a long journey, especially if travelling at night but also on a weekly / bi weekly basis.

If you find a bulb has gone then you may need to visit your local garage or Halfords to get a new one. Some cars are relatively easy to fit new bulbs where as others can even require the front bumper to be removed to allow you to get to it. If you do have to do this then you may have to take a trip to a garage for them to fit the bulb for you. If the other bulbs have not been changed in a while, it may be worth replacing all of them to avoid having to pay labour charges again a few weeks or months down the line.
