During night shift, instead of using the “suicide” light (the big white dome light inside your cruiser) consider replacing the maplight bulbs - located on either side of the Crown Victoria factory dome light - with red ones. They focus light onto your writing and the red light will not hamper your night vision. This also will not light you up like the suicide light, which makes you an easy target.
The red bulbs, common part # 194R, are available from most auto parts stores. Stay safe!
