They don't really need to be radiation shielding or light emitting. People don't need to live there, just plants and animals. And insolation on Mars is sufficient for light.
Is the radiation on Mars excessive? Quick googling suggests 10-20 rem per year, or about half that of the ISS. As far as I know plants do grow on the ISS.
Background radiation in Mars is way lower than would be necessary to kill plants and, like, it might increase cancer rates in animals, but the kind of animals we'd want to breed there have short lifespans and we don't care if they get a few tumors.
