The Collider is shown to have great scope for a light charged Higgs discovery, in context of the C P-violating type-I two Higgs doublet model. This scenario with similar masses of H-+/- and W was suggested by the puzzling departure from charged current lepton universality found in the LEP data. With the lightest neutral Higgs mass set to 125 GeV, the charged-neutral Higgs associated production mechanism can cause a significant excess in the tau nu b (b) over bar events mer a vast range of tan beta as long as the Higgs mixing pattern avoids a few limiting cases. Thanks to the low H-+/- mass, the charged Higgs loop can play a striking role in neutral Higgs decays into gamma gamma, thereby compensating for a suppressed gluon-gluon fusion rate. The effect of scalar-pseudo-scalar mixing on loop-induced Higgs signals is also discussed.
