In this article, we present our results on a global fit to precision electroweak data in a Higgs triplet model. In models with a triplet Higgs boson, a consistent renormalization scheme differs from that of the standard model and the global fit shows that a light Higgs boson with mass of 100--200 GeV is preferred. Triplet Higgs bosons arise in many extensions of the standard model, including the left-right model and the Little Higgs models. Our result demonstrates the importance of the scalar loops when there is a large mass splitting between the heavy scalars. It also indicates the significance of the global fit.
