Most of my exterior bulbs burn out out constantly. Headlights at least once a year, most of the time twice a year. Brake lights/rear license plate bulbs burn out multiple times a year. Fog lights and high beams affected too.

Apart from the annoyance of constantly being pulled over and given verbal warnings, or people yelling at me, trying to help me out by letting me know that yet another bulb is out, it's a safety concern. If I'm braking and the person behind me isn't paying attention, they could slam into me. Where I live durning certain times of the year the fog gets so thick that without fog lights, it's scary to drive. The spot where that 60 car pile up that happen in Virginia a few years ago, is part of my commute. There was a time when a fog light and a head light went out with in minutes of each other, while I was driving in snow.

Now, if the bulbs I have used were cheap ones, then I would be more lenient on them burning out faster. But I'm using top tier Sylvania and Phillips bulbs. These bulbs are expensive and having to change them is costly. I've gone to dealerships and the response is always the same. "Bulbs just burn out, we'll sell you some for $30 each" That's what a Hyundai dealership near me told me when they failed my Sonata's State Inspection. I needed two brake lights.

I know it isn't just my car either. I've been watching Sonata's for probably about a year now, and would you know it, their brake lights are usually out (right side most often) Or their head light is out. A quick Google search is proof enough that I'm not alone.
