The Ford F-150, the best-selling half-ton pickup truck in America for decades was first marketed in 1975, in the F-series' sixth generation. In 2010, the F-series was in its 12th generation, the F-150 its seventh. The 2002 F-150 was among the F-series' 10th generation, which was in production from 1997 to 2003. The 2002 F-150 was available in two- or four-wheel-drive versions and in many different cab, cargo bed and wheelbase combinations. The truck came in three trim levels starting with the base XL, moving up to the midlevel XLT, and on to the top-of-the-line Lariat. The King Ranch and Harley-Davidson F-150s were two special trim levels available in limited numbers. All models utilized high-impact plastic aerodynamic headlamp assemblies that contained replaceable halogen bulbs.
