Thanks Jared but I used wrong descriptive term , I meant the light bulb light that come on on dash that indicates a bulb is out. However at the Auto store I had it brought to my attention that the third break light on top of trunk lid was no longer working. And that could be reason . I am trying to determine the part number so I can order a new digital bulb. On line I see from $25 to $169 so I am totally confused. Anyone has changed the third brake light of 04 Crossfire Coupe and know part number, Please help me, Thanks
