In 1914, Pierce-Arrow adopted its most enduring styling hallmark when its headlights were moved from a traditional placement at the radiator's sides, into flared housings molded into the front fenders of the car. This gave the car an immediately visible distinction in front or side views. At night, the car appeared to have a wider stance. Pierce patented this placement, which endured until the final model of 1938, although Pierce always offered customers the option of conventional headlamps; only a minority ordered this option.
