Detailed Description

This Dorman automatic transmission indicator light bulb is a direct replacement for dash and cluster lighting applications where the gear position display or related indicator has dimmed or stopped working.

This part cross-references Ford OE number F8RZ13B765BA for the same application.

What It Helps Fix
