  Extra light electroweak singlets can dramatically alter Higgs decays by
introducing additional decay modes, $h\to aa$. In scenarios where cascade
decays $h\to aa\to 4X, X\ne b,\bar b$ dominate, the Higgs will escape
conventional searches and may be as light as $82 \gev$. In this paper we
investigate the discovery potential of the mode $h\to aa\to 2\gamma 2g$ through
direct ($pp\to h$) and associated ($pp \to W^{\pm}h$) Higgs production at the
LHC. Our search covers all kinematically allowed singlet masses for $\sim 80
\gev \le m_h < 160 \gev$ and assumes an integrated luminosity $\CL = 300 {\rm
fb}^{-1}$. We find associated production, despite a smaller production cross
section, to be the better mode. A branching ratio $BR(h\to 2\gamma 2g) \cong
0.04$ is sufficient for discovery in the bulk of our search window. Given the
same luminosity and branching ratio 0.04, direct detection fails to discover a
Higgs anywhere in our search window. Discovery in the limited region $m_h > 120
\gev, m_a \sim 25 \gev$ is possible with direct production when the branching
ratio is $\simge 0.06$.
