We examine the influence of additional light Higgs scalars on the predictions of SO(10) both with and without supersymmetry (SUSY) via the one-loop renormalization-group analysis; the breaking pattern SO(10)..-->..SU(2)/sub L-italic/ x SU(2)/sub R-italic/ x U(1)/sub B-italic//sub -//sub L-italic/ x SU(3)/sub C-italic/ is analyzed in particular. We do not find any viable models with a sufficiently long proton lifetime and a correct value of sin/sup 2/theta/sub W/ when M-italic/sub R-italic/ is low (approx. <10/sup 3/M/sub W/). Assuming the SUSY scale M-italic/sub S-italic/ satisfies M-italic/sub S-italic/> or =M/sub R/ we find two models with light colored Higgs scalars which satisfy the experimental constraints. Both models have M-italic/sub R-italic/approx. >10/sup 9/ GeV and M-italic/sub S-italic/approx. >10/sup -2/M/sub U/.
