It features a black outer shell accented by a silver trim ring and includes a white plastic inner mounting core for secure installation. To help you easily identify the current position, there is a single white indicator line on the top of its circular design. This part is useful for drivers who have experienced wear or damage to their original knob and want a functional replacement that fits seamlessly into their dashboard.
