After marker & parking lights became required by law in 1968, the Mustang Marker & Parking Lights have appeared at various locations on the pony car, especially for the front Mustang marker & parking lights. The rear Mustang marker & parking lights have traditionally stayed pretty similar over the years and are usually red rectangular lamps and/or reflectors that are mounted on the rear quarter panel. CJ Pony Parts offers numerous rear Mustang marker & parking lights, including assemblies, bulbs and trim options, so owners of classic and newer muscle cars can complete an upgrade or replacement without any hassle.
