About FER: A Legacy of Vehicle Electrical Excellence
FER — short for Fahrzeugelektrik — carries one of the most storied legacies in automotive electrical engineering. Rooted in the German tradition of precision vehicle electrics, the FER name traces back to the merger of the Ruhla and Eisenach vehicle electrical works, where VEB Fahrzeugelektrik Ruhla became a cornerstone supplier for the entire vehicle electrical needs of an era. At its peak, the manufacturing operation spanned dozens of facilities and employed thousands of engineers and technicians dedicated to producing reliable vehicle electronics.
FER's product range was both wide and technically demanding. The brand manufactured starters, alternators, wiper motors, flashers, brake lights, tail lights, and trumpet horns — supplying not only domestic automakers but also exporting to Western European manufacturers including Volkswagen, Seat, Peugeot, and Citroën. This breadth of OE supply experience gave FER a deep understanding of vehicle electrical systems that carried directly into its aftermarket replacement parts.
Today, FER parts are recognized in the aftermarket as direct-fit, OE-comparable replacements for European vehicles — particularly those from the Volkswagen Group and Porsche lineups. Enthusiasts and professional technicians alike turn to FER when they need a replacement that matches the original specification without compromise.
FER Product Categories
FER's aftermarket catalog focuses on the exterior lighting and signaling components where the brand built its reputation. Whether you need to restore a damaged indicator light or replace a malfunctioning horn, FER offers parts engineered to fit and perform like the factory original.
- Turn Signal Light Assemblies: FER turn signal assemblies are designed as direct OE replacements, matching factory fitment and optical output for European vehicles. These complete housing-and-lens units restore proper signaling function quickly and confidently.
- Horn Kits: With a manufacturing heritage that includes trumpet horns for major European automakers, FER horn kits deliver the tonal quality and electrical compatibility expected from an OE-experienced supplier.
Why Choose FER?
FER parts appeal to owners of European vehicles who want a replacement that mirrors the original design intent. Because the brand's roots are in original equipment manufacturing — supplying parts for production vehicles rather than the aftermarket as an afterthought — FER components are built to OE tolerances. For vehicles like the Volkswagen Touareg or Porsche models, where fit and finish matter as much as function, FER's turn signal light assemblies and horn kits offer a trusted path back to factory specification.
