Three miniature label-less oil barrels were included in the redesigned 1975 Hess Box Trailer. In addition to working headlights and taillights, this 1975 Hess truck had sliding side doors and rear doors that swung open on the back of the trailer. A switch to turn on the lights was located on the bottom of the trailer. The green livery on this edition is somewhat lighter than later years. Only 500,000 of these trucks were made for the 1975 holiday season.
