  We study the influence of the angle between the two dipole transition moments
on the group velocity for two kinds of three-level V-type systems with
spontaneously generated coherence and incoherent pumping. The group velocity of
the probe field for both kinds of the V-type systems alternates between the
subluminal or superluminal regimen. We can choose a real three-level V-type
system from atoms or molecules to exhibit subluminal or superluminal light
propagation by a proper geometry of the probe, coupling and incoherent pumping
fields, which depends on the angle between the two dipole transition moments.
