It’s a known fact in the automotive industry that companies under the same ownership often share parts to reduce costs and streamline production. Daimler-Benz’s acquisition of Freightliner in 1981 is a prime example of this. By 1992, Freightliner had become the largest heavy-duty truck producer in North America under Daimler’s wing. This collaboration, while economically sound, sometimes leads to surprising parts sharing across different vehicle types. You might expect shared components within the same brand, but the stark contrast between Freightliner’s robust semi trucks and the luxury automobiles of Mercedes-Benz makes the reality of parts interchangeability quite intriguing. For years, subtle hints, like suspiciously Mercedes-esque lights on Freightliner trucks, piqued my curiosity, leading me to investigate this cross-market component sharing.
The most immediately recognizable instance of this parts sharing, at least for me, is the turn signals on older Freightliner FLD120 semi trucks. These iconic corrugated turn indicators bear a striking resemblance to those found on numerous Mercedes-Benz models from the 1970s and 1980s. My suspicions were confirmed through research: these turn signals are indeed interchangeable between the Mercedes-Benz W124 E-Class and the Freightliner FLD120 semi trucks. If you’re looking to replace a turn signal on a 1986-1993 Mercedes E-Class, the part number MB2520104 will also fit certain Freightliner FLD120 semi trucks, as confirmed by parts listings on platforms like eBay. This seemingly small detail highlights the depth of integration between these seemingly disparate brands under the Daimler umbrella, showcasing how even a Mercedes Benz Semi Truck could incorporate design elements from its passenger car siblings.

Beyond turn signals, another instance of shared components, one that was less obvious to me initially, involves the headlights. The first-generation Mercedes-Benz ML-Class SUV (W163) shares its headlights with certain 2003-2006 Freightliner Columbia semi trucks. Growing up, the Freightliner Columbia was a common sight on the roads, and realizing this connection now adds a layer of fascination every time I see one. The headlight, part number 3401103LAS, serves double duty, fitting both the early ML-Class SUVs and the Freightliner Columbia semi trucks. This is a testament to efficient design and manufacturing across Daimler’s diverse vehicle portfolio, impacting everything from luxury SUVs to a mercedes benz semi truck component supply chain.
While these headlights might not possess the same distinctive design flair as Mercedes-Benz’s corrugated turn signals, the fact remains: they are a shared component. It’s perhaps less surprising that this connection went unnoticed by someone like me, who prides himself on identifying the passenger car origins of lights on even less common vehicles. The next time you encounter a Freightliner truck on the road, take a closer look at its lights. You might just spot some Mercedes DNA hidden in plain sight. Just remember to keep your focus on the road if you are behind the wheel!
