On a 2005 Ford F350, the low beam relay is typically located in the engine compartment fuse box. You can find the fuse box near the driver's side of the engine bay, near the battery. The relay is usually labeled, so refer to the diagram on the cover of the fuse box for specific identification. Always ensure the vehicle is turned off and take care when working with electrical components.
