  Localization of electromagnetic waves in disordered potentials is prevented
by polarization terms, so only light scattering systems of dimensions $d=1$ and
$2$ with scalar properties exhibit light localization. We here show that this
result breaks down due to the existence of surface modes, which possess
lower-dimensional scattering properties. In particular, vectorial waves in $3D$
($2D$) presents surface localized modes with scaling consistent with
localization $2D$ ($1D$)
