It might come as a surprise to many, but Mercedes-Benz, renowned for its luxury vehicles, has a significant footprint in the North American semi-truck industry. Following Daimler-Benz AG’s acquisition of Freightliner in 1981, Freightliner became the dominant heavy-duty truck producer in North America by 1992 under Daimler’s management. This cross-market relationship led to an intriguing phenomenon: parts sharing between Mercedes-Benz automobiles and Freightliner trucks. While parts sharing within company groups is common, the extent to which components from Mercedes-Benz passenger cars found their way into Freightliner semi trucks is quite remarkable, especially when you consider the distinct markets they serve. For years, keen observers have noticed familiar Mercedes-Benz design cues in Freightliner trucks, prompting a closer look into this automotive connection.
One of the most immediately recognizable instances of parts sharing can be seen in the turn signals of older Freightliner FLD120 semi trucks. These iconic corrugated turn indicators bear a striking resemblance to those featured on numerous Mercedes-Benz models throughout the 1970s and 1980s. Further investigation reveals that these aren’t just similar in appearance; they are indeed interchangeable parts. The turn indicators from the 1986-1993 Mercedes-Benz E-Class (W124), bearing part number MB2520104, are compatible with certain Freightliner FLD120 semi trucks, as confirmed by parts listings. This means a component designed for a luxury sedan was also utilized in a workhorse semi truck.

Another surprising example of this automotive cross-pollination lies in the headlights. Unbeknownst to many, the headlights from the first generation Mercedes-Benz ML-Class SUV (W163) were also used in 2003-2006 Freightliner Columbia semi trucks. The Freightliner Columbia is a common sight on North American roads, and knowing this connection adds a new layer of interest to these vehicles. The headlight assembly, part number 3401103LAS, is interchangeable between the early ML-Class SUVs and Freightliner Columbia semi trucks. While these headlights may not possess the same distinctive design as the corrugated turn signals, the fact remains that a core lighting component from a Mercedes-Benz SUV found its application in a heavy-duty semi truck.
These instances of parts sharing highlight the practicalities and synergies within large automotive groups like Daimler (now Mercedes-Benz Group). Next time you encounter a Freightliner semi truck on the road, take a closer look at its lights. You might just spot some unexpected Mercedes-Benz DNA embedded within these titans of the highway.
