LRS Bianchi type-I models have been studied in the cosmological theory based on Lyra's geometry. A new class of exact solutions has been obtained by considering a time dependent displacement field for constant deceleration parameter models of the universe. The physical behaviour of the models is exa

Abstract
The inner metric of general light cone in a BIANCHI type I geometry is determined. No focal surface can occur. The singularities which appear in the cosmological solutions of the EINSTEIN field equations at some past instant of time are shown to appear also as singularities of the inner light cone geometry. The behaviour of null geodesies constituting the light cone is studied in the neighbourhood of their singularities.
