Assuming flat universal extra dimensions, we demonstrate that for a light Higgs boson the process pp→ W^*W^* +X → Higgs,graviscalars +X → invisible+X will be observable at the 5 σ level at the LHC for the portion of the Higgs-graviscalar mixing (ξ) and effective Planck mass (MD) parameter space where channels relying on visible Higgs decays fail to achieve a 5 σ signal. Further, we show that even for very modest values of ξ the invisible decay signal probes to higher MD than does the (ξ-independent) jets/\gam + missing energy signal from graviton radiation. We also discuss various effects, such as Higgs decay to two graviscalars, that could become important when mh/MD is of order 1.
