Loosen the screw from one original equipment passing lamp trim ring and remove the ring.

See the Service Parts illustration. Remove the screw (3) and nut (2) from the accessory trim ring (1) and set aside temporarily.

If not already installed, place the rubber strip (4) inside the trim ring. Align so the gap in the rubber strip is opposite the split in the trim ring as shown.

Insert the passing lamp sealed unit (C) inside the new trim ring and rubber strip assembly.

Position the bottom of the lamp unit to line up with the split in the trim ring.

For 2002 and later models Install the adapter ring (D) onto the passing lamp housing, lining up the tab on the ring with the notch in the lamp housing. Install the trim ring and lamp assembly onto the adapter ring, aligning the lug (or lugs) on the back of the glass lamp unit with the notches in the adapter ring. For 1962 through 2001 models Install the trim ring and lamp assembly onto the passing lamp housing, aligning the lug (or lugs) on the back of the glass lamp unit with the notches in the passing lamp housing.

Assemble the screw and nut to the trim ring and tighten securely.
