protect the grille, while others have extensions that shield as far as the headlights. Some pushbars also have emergency lights installed on them, providing additional visual warnings. Spotlights Spotlights are small searchlights typically installed on the A-pillar of a police car. They are used to provide light in darkened areas or where necessary, such as down alleyways or into a suspect's car during a nighttime traffic stop. These spotlights can be aimed and activated by the officers inside the vehicle. Usually, one or two are installed on the car, though more may occasionally be installed on the roof, grille, bumper, or pushbar. Run lock Run locks allow the vehicle's engine to be left running without the keys being in the ignition. This allows adequate power to be supplied to the vehicle's equipment at the scene of an incident without battery drain. The vehicle can only be driven after inserting the keys; if the keys are not inserted, the engine will switch off if the handbrake is disengaged or the footbrake is activated. Ballistic protection Some police cars can be optionally upgraded with bullet-resistant armor in the car doors. The armor is typically made from ceramic ballistic plates and aramid baffles. A 2016 news report said that Ford sells 5 to 10 percent of their American police vehicles with ballistic protection in the doors. In 2017, New York City Mayor Bill de Blasio announced that all NYPD patrol cars would have bullet-resistant door panels and bullet-resistant window inserts installed.
