Dongfeng KC Left Front Combination Lamp Assembly 3772010-C0104

Low Beam: Adopts a parabolic reflector with a 12° light cutoff angle, providing a uniform light pattern that illuminates 35-40 meters ahead without dazzling oncoming drivers, meeting ECE R112 low-beam safety standards

High Beam: Features a multi-faceted reflector that concentrates light to reach 80-100 meters ahead, enhancing long-distance visibility for night driving on highways or rural roads.

Turn Signal: Uses a high-brightness amber LED (luminous flux: 120lm) with a flash frequency of 60±5 times per minute, ensuring clear warning signals even in strong sunlight.

Position Light: Equipped with 6 warm-white LEDs (total luminous flux: 80lm) for 24-hour vehicle contour indication, improving driving safety in low-light conditions

Lamp Housing: Made of PC+ABS alloy plastic with a 2.5mm thick wall, featuring high impact resistance (passing 1.5m drop test with no cracks) and excellent heat resistance (operating temperature range: -40℃ to +85℃), effectively resisting deformation caused by engine heat or extreme weather.

Lens: Adopts UV-resistant PMMA material with a hard coating (hardness: HRC 2H), preventing yellowing and scratches after 3,000 hours of sunlight exposure—maintaining 90% light transmittance for long-term use.

Internal Components: The circuit board is coated with a 0.2mm thick waterproof conformal coating (IPX7 waterproof rating), and the wire connector uses a Delphi sealed plug to avoid short circuits caused by water or dust intrusion

Every unit of this assembly undergoes 8 strict quality inspections before leaving the factory, including:

Waterproof testing (immersion in 1m deep water for 30 minutes with no water ingress).

Vibration testing (10-500Hz frequency, 3-axis vibration for 2 hours to simulate road

Thermal shock testing (-40℃ to +85℃ cyclic temperature changes for 50 cycles).

Light intensity testing (ensuring low beam ≥1500cd and high beam ≥18000cd).

With these tests, the assembly achieves a service life of over 5,000 hours, 30% longer than ordinary aftermarket alternatives

Mounting Structure: Uses a 4-point bolt-on design (M6×16 stainless steel bolts included) that aligns with the original vehicle’s mounting brackets—professional technicians can complete installation in 20-30 minutes, and no welding or drilling is required.

Maintenance Accessibility: The LED bulbs and fuse (10A ceramic fuse) are installed in a detachable rear cover; if a bulb fails, users only need to unscrew 3 screws to replace the bulb, without disassembling the entire assembly.

Labeling & Documentation: Each unit is labeled with the part number, production date, and batch code for traceability, and a 2-page installation manual (with diagrams of mounting points and wiring connections) is included to guide proper use
