Reasons to have a certified dealer change your headlight bulbs
It's not uncommon for headlight bulbs to die out over time, especially if you drive on a regular basis. You may decide that a single headlight being out isn't a big deal, but most states require both headlights to be working once the sun sets. If you realize your headlight is out, think twice before having a typical auto parts vendor fix the problem.
Many vehicles are designed so that the headlights can't be accessed without doing a little maneuvering underneath the hood. If you opt to change the bulb yourself, there's a good chance that you could accidentally misplace essential components when tampering with the front headlights. Additionally, a mechanic who is unfamiliar with your particular make and model might take more time to understand the configuration, and thus charge more money.
Even though a headlight bulb might seem like a little problem, it's extremely necessary to have both lights working when the sun sets. Going through a certified dealer is the most reliable way to address the problem in a speedy and affordable manner.
