摘要：
Fahrzeugscheinwerfer, umfassend einen Kabelkanal (1, 2, 3, 4, 5), der eine vordefinierte Form entsprechend einem Verlauf innerhalb des Fahrzeugscheinwerfers aufweist. Der Kabelkanal (3) umfasst zumindest zwei entlang einer Längsrichtung verlaufende Kabelbahnen (310, 320), die sich jeweils in Längsrichtung (50) zwischen zwei Bahnenden (316, 317, 326, 327) erstrecken. Jede Kabelbahn (310, 320) weist quer zu ihrer Längsrichtung einen im Wesentlichen U-förmigen Querschnitt, der durch zwei Schenkel (311, 321, 312, 312) und eine Basis (313, 323) gebildet ist, auf, wobei die Schenkel (311, 312, 321, 322) über die Basis (313, 323) miteinander verbunden sind und die Schenkel jeweils offene Schenkelenden (314, 315, 324, 325) aufweisen. Die zumindest zwei Kabelbahnen (310, 320) sind in Längsrichtung (50) aneinander anreihbar, sodass sie in einer gedachten Verlängerung des im Wesentlichen U-förmigen Querschnitts gelegen sind und voneinander durch eine Unterbrechung zumindest der Basis (313, 323) getrennt sind, wodurch sie hinsichtlich der Unterbrechung und zueinander einen Abstand (319) in Längsrichtung (50) aufweisen, und die erste Kabelbahn (310) mit der zweiten Kabelbahn (320) an deren einander zugewandten Bahnenden (317, 326) über zumindest eine Brücke (318) verbunden ist.
