The Dodge Ram 50 (called the Dodge D-50 for 1979 and 1980) was a badge-engineered version sold by the Chrysler Corporation from 1979 on. The label lasted until 1994, through two generations. Plymouth also received a version of the vehicle known as the Plymouth Arrow Truck, sold from 1979 to 1982. This was Chrysler's belated answer to the Ford Courier from Mazda and the Chevrolet LUV by Isuzu (both of which had been introduced in 1972), while the Toyota Hilux and Datsun Truck were already available and imported directly from Japan. Mitsubishi itself imported it as the Mitsubishi Mighty Max when it began selling directly in the US from 1982, at which point the Plymouth ceased to be available. The Dodge version had quad rectangular headlights beginning with the 1983 facelift, while Mitsubishis and earlier Dodges had single units in North America. In the rest of the world, importers could choose between single or double rectangular units, as well as twin round headlights. The twin round units were the original fitment for the Japanese domestic market.
