Some embodiments of an infusion pump system may include an illumination instrument that provides the user with an opportunity to illuminate and inspect a targeted location. The illumination instrument can be useful in situations where the ambient lighting is insufficient for the user's inspection needs (e.g., during the night, during presentation or movie in which the lighting is low, or the like). In some embodiments, illumination instrument can be employed to visually inspect one or more components of the pump system, the infusion set, or a combination thereof.
