A generalisation of the Stueckelberg action is implemented to describe spin-1 fields propagating in a four-dimensional Rindler manifold. Exact solutions of the field equations are obtained and the expectation value in the Minkowski vacuum state of the Rindler particle number operator is evaluated in the massive and massless cases. Further on, the energy-momentum tensor expectation value in the Rindler vacuum is computed and its qualitative behavior is analysed. In the zero mass limit we rederive the results obtained by other methods. Like this case, in the massive one it is shown that the energy-momentum spectrum is not Planckian. For small values of the mass, this spectrum is characterised by the Bose distribution function apart from a modification generated by a reduced density of states factor which is explicitly calculated.
