Right Side Repeater Lamp - 1987 Mustang

The right side repeater lamp (side marker) on the 1987 Ford Mustang marks the debut of the aero nose redesign, originally cataloged under Ford service number E7ZZ-15A201-A. These assemblies interchange across all 1987-1993 Fox-body Mustangs regardless of LX, GT, or SVO variants, though subsequent supersessions like F1ZZ-15A201-A offer identical geometry with improved UV-resistant lens compounds. When pulling from salvage yards, scrutinize the amber lens for stress cracks and the plastic mounting studs that commonly shear during removal. The 194 bulb socket often suffers from terminal corrosion or heat damage—test continuity through the ground wire. Installation requires accessing the inner fender splash shield to reach the single retaining nut; always replace the rubber grommet to prevent water intrusion into the fender cavity. Verify the wiring pigtail length, as some early 1987 production units featured shorter leads than 1988-1993 models.
