Narrative:
Filed at FL280; assumed because of strong headwinds and an attempt by the 'default' flight plan to make an on-time arrival. Over the gulf of mexico turbulence became 'moderate' and I elected to climb to a higher altitude. At no time did I realize that the 'altitude alert' light 'inoperative' would restrict us from the higher altitudes. I just didn't realize that we were restr to lower; if we indeed were.
