Description of Change: A new lamp group (backup lamp group) is being used on all articulated trucks. The new lamp group is more resistant to shock and vibration damage.

Adaptable To: The new 122-6663 Lamp Group is being installed on all articulated trucks in production. The new 122-6663 Lamp Group can be used as a replacement for the former 9X-1439 Lamp Group which is still serviced. The new lamp group uses a 9X-3463 Bulb which is replaced by removing the four screws that hold the bezel and lense on the lamp group.

When replacing the former 9X-1439 Lamp Group with the new 122-6663 Lamp Group, an 8T-4133 Nut and 8T-4121 Washer is needed to mount the new lamp group.
