1. A lighting system for illuminating a cooking cavity in a cooking appliance, comprising:
a light guide rod configured to guide an illumination;
a reflective element optically coupled to the light guide rod for reflecting the illumination from the light guide rod toward the cooking cavity; and
a guide for insertion of the light guide rod extending longitudinally between an insertion end and a reflective element connection end coupled to the reflective element, the guide defining an inner surface that is tapered, becoming narrower from the insertion end towards the reflective element connection end, for guiding the light guide rod during optical coupling with the reflective element.
