Good morning XF enthusiast...for quite some time my trunk light wasn't working. I just never cared to replace it until last week. The auto store gave me the wrong size bulb. It was a centimeter or two short and caused a few sparks while I was trying to install it. A few days later I noticed that the interior lights were not coming on also. I took out the plastic housing to look at both bulbs and they looked fine. When I finally purchased the correct bulb size for my trunk, it did not come on as well so I figured that it was relative to the interior light. Apparently a fuse or something blew however, I cannot find out where it is at. I looked at the fuse box near the driver side door and the chart does not indicate that any of the fuse outlet is for the interior lights. Someone told me that it could be under the hood but before I go messing around, I thought that it would be wise to query this on here. Can somebody give me any insight on this matter, thanks.
