  In the Majoron models the $SU(2)$ doublet Higgs can decay invisibly into a
Majoron pair via its mixing with a singlet. An analysis of the LEP data shows
the invisible decay mode to be more visible than the SM decay. For these
models, the dominantly doublet Higgs $H$ is shown to have a mass limit within
$\pm 6$ GeV of the SM limit irrespective of the model parameters. But the
dominantly singlet one $S$ can be arbitrarily light for sufficiently small
mixing angle.
