1. A method for indicating a state of a pharmaceutical delivery device to a user, the method comprising:
optically coupling a light source to a cartridge, the cartridge comprising:
a reservoir containing a fluid;
a light pipe with a light input location; and
a light diffusing section optically coupled to the light input location;
positioning the light source and the cartridge in a housing of the pharmaceutical delivery device, the housing comprising a window;
aligning the light diffusing section with the window of the housing to provide an optical pathway between at least part of the light diffusing section and an outside of the housing; and
operating the light source to indicate a state of the pharmaceutical delivery device via diffusion of light from the light source through the light diffusing section and to the outside of the housing through the window.
