There is an easier way to replace your fog light bulbs other than having to go through the fender liner. Both fog lights can be reached by reaching from the bottom underneath the front. Most posts/videos I've seen showed that you need to remove the fender liner. Finally replaced the driver side factory OEM bulb after owning for 7years since new. I saw this vid and realized you can do the same on the driver side. Cheers!
