It has been suggested that two different excesses of events observed at CERN LEP could be interpreted as the CP-even Higgs bosons of the minimal supersymmetric standard model (MSSM) with masses of approximately 98 and 114 GeV. If this is the case, the entire MSSM-Higgs sector is required to be light. In this article, we explore such a scenario in detail. We constrain the Higgs and supersymmetric spectrum using B physics constraints as well as the magnetic moment of the muon. We then point out the implications for neutralino dark matter---next generation direct detection experiments will be sensitive to all MSSM models with such a Higgs sector. Finally, we find that all models outside a very narrow corridor of parameter space have a charged Higgs boson which will be observed at the CERN LHC. In those exceptional models which do not contain an observable charged Higgs, a light top squark will always be seen at the LHC, and likely at the Tevatron.
