3772010-C6203 Headlamp Assembly is the integrated front combination lamp for DFL KX heavy truck cab. It integrates low beam, high beam, daytime running light and turn signal modules into one compact unit, delivering clear road illumination for night driving, foggy conditions and lane changing reminders. This aftermarket replacement assembly resolves dim light output, water fogging inside the housing, broken lens and intermittent light failure caused by cracked outer cover, corroded circuit board and aging light source of original lamps. Stable lighting performance enhances driving visibility and traffic safety for long-haul trucks traveling at night and in low-visibility environments.
Product Advantages Polycarbonate lens with anti-UV coating resists yellowing and sand abrasion on rough roads. Sealed housing structure reduces the risk of water vapor condensation inside the lamp cavity. Built-in high-efficiency LED light module offers lower power consumption and longer service life than halogen lamps. Each lamp undergoes lighting brightness, waterproof and vibration resistance testing before shipment, factory mounting hole layout for direct plug-and-play installation.
