We investigate the influence of the Higgs scalars in an SO(10) grand unified model. Special emphasis is laid on whether or not we can construct an SO(10) model having light SU(2)_R weak bosons and the proton decays with a measurable lifetime of Θ(10^<30~31> years). Inclusion of a few antisymmetric 5 rank {126} tensors makes us possible to lower the grand unification mass scale down to Θ(10^<14> GeV) and to have the SU(2)_L×SU(2)_R×U(1)_<B-L> electroweak symmetry restored around (100~300)GeV with the reasonable values of a_s and sin^2θ_w. Furthermore, we can implement the extended color Su(4) symmetry around the mass scale 10^<11> .
