Dongfeng KL truck parts Right front combination lamp assembly 3772020-C3304

Designed as an all-in-one front lighting solution, the assembly integrates five core functions: right turn signal, daytime running light (DRL), low beam, high beam, and position light—eliminating the need for separate single-function lamps. The right turn signal uses 10 amber SMD LEDs (350 lumens, 6000K) with a flash rate of 60–120 flashes per minute; the DRL features 12 cool white LEDs (400 lumens) that meet ECE R87 standards for daytime visibility; the low/high beams use high-performance LED chips (1200 lumens low beam, 2000 lumens high beam) with a 120° beam angle for broad road coverage; and the position light includes 6 warm white LEDs (80 lumens) for nighttime presence. This integration simplifies wiring (single 8-pin connector) and reduces component redundancy, unlike scattered lamps that increase failure risks and complicate maintenance

Engineered to maximize visibility while avoiding glare for oncoming drivers, the assembly features optimized optical design. The low beam uses a precision reflector that creates a sharp light cutoff (meeting ECE R112 standards), preventing light from dazzling oncoming traffic while illuminating the road up to 50 meters ahead. The DRL’s 400-lumen output ensures the truck is visible to other vehicles from 1000+ meters in daylight, reducing collision risks during morning or evening commutes. The turn signal’s amber light has a color rendering index (CRI) of 90+, making it easily distinguishable from other lights (e.g., white DRLs) even in fog or rain. Unlike generic lamps with uneven light distribution, this design ensures reliable signaling and road illumination in all weather conditions

Built to withstand the harsh conditions of commercial truck use—including road debris impact, vibration, and extreme weather—the assembly features a durable structure. The housing is made of impact-resistant ABS plastic (UL94 V-0 flame-retardant rating) that resists cracks from gravel impacts or minor collisions and maintains rigidity in temperatures ranging from -40°C to 95°C. The lens is a 5mm-thick polycarbonate sheet with a dual-layer coating: a scratch-resistant layer (resisting damage from truck washes or road debris) and a UV-resistant layer that prevents yellowing for 6+ years. The assembly meets IP68 waterproof/dustproof standards: a rubber O-ring seals the housing-lens junction, and a sealed 8-pin connector blocks moisture intrusion—avoiding short circuits from heavy rain, snow, or road salt

Designed for efficient replacement by fleet technicians or DIY owners, the assembly simplifies installation with user-friendly features. It includes 5 OEM-matched bolts (M6×25mm) that fit the truck’s existing front bumper holes, requiring no drilling. The 8-pin electrical connector is keyed and color-coded to match Dongfeng KL’s wiring harness, eliminating reverse polarity or miswiring (which damages lamps or the truck’s electrical system). Installation takes 30–35 minutes with standard hand tools (e.g., socket wrench), as the assembly aligns perfectly with the front bumper’s reference marks. The combination lamp complies with global safety regulations (ECE R10 for electromagnetic compatibility, FMVSS 108 for lighting performance) and is certified for use in major markets (EU, North America, Asia). Backed by a 30-month warranty against manufacturing defects (e.g., LED failure, lens cracking, waterproof seal damage), it provides Dongfeng KL truck owners with reliable front signaling and long-term safety
