This is the genuine \u003cstrong\u003eFreightliner Drive\/Marker Light Module\u003c\/strong\u003e, the OEM control unit that drives the \u003cstrong\u003edaytime running lamp, turn signal and marker\u003c\/strong\u003e functions of the \u003cstrong\u003eNew Cascadia LED headlight system\u003c\/strong\u003e. When one of those sections goes dark, flickers, or throws a lamp out fault while the bulbs and the wiring test good, this module is the part to check, and replacing it restores correct lighting operation without swapping the entire headlamp. We stock genuine Freightliner electrical parts right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.\u003c\/p\u003e\n\n\u003ch2\u003eThe Part That Actually Failed: The Cascadia Light Module Advantage\u003c\/h2\u003e\n\n\u003cp\u003eThe module sits \u003cstrong\u003einline with the headlight assembly\u003c\/strong\u003e and regulates the \u003cstrong\u003evoltage and switching the LED segments need\u003c\/strong\u003e. That is why a failed module looks exactly like a failed headlight from the driver's seat: a dead daytime running lamp, a flickering marker strip, or a turn signal that will not light, all with good bulbs and good wiring behind it. Diagnosing that as a headlamp failure is an expensive mistake, because a New Cascadia LED headlight assembly costs many times what the control module does.\u003c\/p\u003e\n\n\u003cp\u003eThis is the genuine \u003cstrong\u003eFreightliner\u003c\/strong\u003e part rather than a look-alike, which matters on a component whose whole job is regulating voltage to an expensive LED assembly. It is the direct answer for the highly searched numbers \u003cstrong\u003e66-01405-030\u003c\/strong\u003e and \u003cstrong\u003eZKW 1040.001.0920\u003c\/strong\u003e.

At FleetPro Parts \u0026amp; Tires we would rather sell you the module that failed than the headlamp that did not, so check this part first when a Cascadia headlight section quits and the harness tests clean.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eVehicle Fitment \u0026amp; Compatibility\u003c\/h3\u003e\n\u003cp\u003eThis genuine OEM control module is intended for the following commercial application:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMake\/Model:\u003c\/strong\u003e Freightliner Cascadia (P4) 2018-2025\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSystem:\u003c\/strong\u003e New Cascadia LED headlight system, drive and marker control\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Daytime running lamp, turn signal and marker lighting\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Wires inline with the headlight assembly\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComponent Group:\u003c\/strong\u003e Exterior Lighting \/ Headlight Control Modules\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eDirect Replacement \u0026amp; Cross-Reference Numbers:\u003c\/h3\u003e\n\u003cp\u003e\u003cem\u003eThis genuine Freightliner module serves as a direct replacement for the following part numbers:\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFreightliner Interchange:\u003c\/strong\u003e 66-01405-030\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eZKW Interchange:\u003c\/strong\u003e 1040.001.0920\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e LED headlight control module\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Controls daytime running lamp, turn signal, and marker lighting\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOperation:\u003c\/strong\u003e Regulates voltage and switching to the LED light segments\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Inline with the headlight assembly\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Freightliner Cascadia (P4) 2018-2025\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e New\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-Year FleetPro Warranty\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Freightliner (Distributed by FleetPro Parts \u0026amp; Tires)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Freightliner","offers":[{"title":"Default Title","offer_id":43036193783879,"sku":"66-01405-030","price":165.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/8035\/2583\/files\/image_1920_af2a19ab-5b17-4fbf-bd72-31d42de82d26.webp?v=1787697281","url":"https:\/\/fleetpropt.com\/products\/oem-freightliner-drive-marker-light-module-new-cascadia-2018-2025-led-headlight-control-zkw-1040-001-0920-66-01405-030","provider":"FLEETPRO PARTS \u0026 TIRES","version":"1.0","type":"link"}
