Welcome aboard! We have vehicle chargers for the flashlights, so one light is in the charger, one is on my person. Extra 123 batteries for the tactical light, nitrile gloves and antimicrobial wipes in a zip-lock bag in a pocket, extra radio battery in the case in the car, first aid kit for ME in the car (tailored for my allergies, cuts, and scratches that go with the job, but now also containing self-injectors for nerve agents <img src="/images/graemlins/mad.gif" alt="" />), cheat card in pocket with access codes and locations of shelters and prepared resupply areas (other than the station), wide-area map book in the car, personal cell phone (on different carrier than the department issue phone).

That is what comes to mind. If I remember, I will take a look at my duty case next week and see what else is hiding in the corners.
