The International Light Line pickups replaced the C-Series as International’s Light Line range of pickup trucks in early 1969. It was largely a rebodied version of its predecessors, with a square-rigged look very similar to the period Scout utility vehicle. The Travelall underwent parallel changes to the Light Line trucks. The light line of trucks was marked by a larger range of transmission and wheelbase options than any of its competitors, and in general the lineup aimed to maximize adaptability. The Light Line was also available as a bare chassis, for special purpose applications.

For 1971 the Light Line underwent a slight styling change, now with a plastic grille. The naming system also changed, with the “D” being dropped and with a “10” being added in the series number. Thus, the new trucks were labeled 1010 through 1510, depending on weight ratings. The engine range was the same as for the earlier pickups, although AMC’s 258 six was added later in 1971. The smaller 232 was dropped for 1972, as was the 266 V8 which had still been available in early 1971. From that year on a metal grille with five horizontal bars and a slim central vertical opening was installed instead of the previous plastic unit.

The 1010 and 1110 have the same weight rating, the difference being in the front suspension: independent, by torsion-bars, for the 1010, and of a solid I-beam construction for the 1110 (and all heavier versions). A first for the segment was the option of a Bendix anti-lock brake system called Adaptive Braking System by International. Operating only on the rear wheels, it was made available to the pickups (and Travelalls) in late 1971. Due to the expense of this novel system, it was a rarely selected option.
