The stimulus in the pupil reflex would be light
The pupil dilates when stimulated by the pinching on the nape of the neck.
Edinger-Westphal nucleus of the brainstem controls the pupil reflex. An ER doctor who looks at the response to a pen light is checking on brain stem activity.

the pupil gets smaller because there is an abundance of light present.

Pupils reacts to light, narrowing in bright light and widening in poor light - so is a reflex action.

The constriction of pupils in response to bright light is called the pupillary light reflex. If the light is shining directly into one eye, then the pupil in that eye will constrict (a direct response), but so will the pupil in the non-illuminated eye (a consensual response).This reflex involves two cranial nerves: the optic nerve, which senses the light, and the oculomotor nerve, which constricts both pupils. It is considered involuntary since you don't think about it.

Reflex action is your body's reflex against injury. It is needed in every part of your body.
