LTD was given a styling update. In the rear, the long-running Ford styling tradition ended as the twin round or square "jet exhaust" taillights were replaced by horizontal taillights on all full-size Fords. In between the two tail lamps was a center "third" brakelight; on the Galaxie 500, this space was an alloy trim panel while Custom 500s had body-color trim. In front, the LTD lost its hidden headlamps to Lincoln-Mercury, but got a new front end treatment with a tall center grille section and "LTD" spelled out in block letters on the hood. With the discontinuation of the XL series, the convertible was moved to the LTD line. These were produced with bucket seats and center consoles; the console was similar to the console in the XLs and Mercury Marauders of 1969–1970, with a "stirrup" style shift handle. A modified 1971 Ford Custom is featured prominently in the 1973 American film White Lightning. It is the car driven by the film’s lead character, portrayed by Burt Reynolds. 1972: 1972 models were virtually the same as the 1971s, although the bumper now stretched across the lower section of the grille. A new rear bumper integrated the taillights; also in the rear, the design of the trunklid was squared off. Due to decreased demand in the segment, 1972 was the final model year for the LTD convertible. 1973: In 1973, in order to comply with federal regulations, the LTD was given a major redesign for the model year. The requirements for 5-mph front bumpers had taken effect, with larger rear bumpers to be added in 1974. While the redesign slightly decreased the weight of the LTD, it still was far in excess of two tons, making agility and fuel economy both key weak points. The new styling was bulkier, making the car look significantly larger and heavier than previous models. Four-door models (sharing rooflines with Mercury) were given thin B-pillars for roof reinforcement and branded as "pillared hardtops" (frameless door glass remained on all Ford LTD models). The 460 engine became an option for the first time in 1974. 1974: Five-mph bumpers added to the rear. Mostly carryover from the 1973 model year. Mid-year, a non-woodgrain LTD wagon became available. A new Federal law required seat belts to be buckled before the starter would operate; public protests prompted the government to relax this requirement. Subsequent models got a simple "Fasten Seat
