We use the, covariant and gauge-invariant, 1+1+2 formalism developed byClarkson and Barrett, and develop new techniques, to decouple electromagnetic(EM) perturbations on arbitrary locally rotationally symmetric (LRS)space-times. Ultimately, we derive 3 decoupled complex equations governing 3complex scalars. One of these is a new Regge-Wheeler (RW) equation generalizedfor LRS space-times, whereas the remaining two are new generalizations of theBardeen-Press (BP) equations. This is achieved by first using linear algebratechniques to rewrite the first-order Maxwell equations in a new complex 1+1+2form which is conducive to decoupling. This new complex system immediatelyyields the generalized RW equation, and furthermore, we also derive a decoupledequation governing a newly defined complex EM 2-vector. Subsequently, a furtherdecomposition of the 1+1+2 formalism into a 1+1+1+1 formalism is developed,allowing us to decompose the complex EM 2-vector, and its governing equations,into spin-weighted scalars, giving rise to the generalized BP equations.
