Have the same problem today on the Limited. Just before pulling into the garage the bulb out light came on. I have DRL's so all lights on all the time. I did a walk around and didn't find any lights out. Both license plate lights are working, I changed one about a week ago, all side markers, I pulled the lenses to be sure, positioning lights in the headlamps are OK, high and low beam, all signals work and brake lights work, I checked the fogs but I still get that darn light! I ended up removing my HID's and replaced with stock bulbs just to be sure, but no love light is still on. I tried to check the back-up lights, ignition on run position and car in reverse but no lights. Should they be on or does the car need to be running? Any ideas?
