  The light cone method provides a convenient non-perturbative tool to study
the heavy-to-light form factors. We construct a light cone quark model
utilizing the soft collinear effective theory. In the leading order of
effective theory, the ten $B$ to light physical form factors are reduced to
three universal form factors which can be calculated as overlaps of hadron
light front wave functions in the light cone quark model. The numerical results
show that the leading contribution is close to the results from other
approaches. The $q^2$ dependence of the heavy-to-light form factors are also
presented.
