Dongfeng KInland truck parts Position lamp assembly 3731010-C0100

Equipped with a 2W high-performance LED light source (4pcs 0.5W SMD LEDs), the position lamp delivers a uniform luminous flux of 180 lumens with a 3,000K warm white light—meeting ECE R7 and GB 4785 standards for position lamp brightness (minimum 150 lumens). The LED chips are arranged in a linear pattern and covered with a light-diffusing PC lens (transmittance ≥90%), ensuring the lamp is visible from 1,000 meters away in dark environments while avoiding glare to oncoming vehicles. The LED lifespan exceeds 50,000 hours—10 times longer than traditional incandescent bulbs—eliminating frequent replacements for Kinland trucks in long-haul operations (e.g., cross-country transport with 24/7 running time). Additionally, the lamp’s power consumption is only 0.17A at 12V, reducing battery load compared to incandescent alternatives (0.5A), which is critical for trucks using multiple electrical accessories

Engineered to withstand the harsh conditions of truck operation—rain, snow, road dust, and temperature fluctuations—the position lamp assembly achieves an IP67 protection rating. The housing is made of high-impact PC plastic (impact strength ≥50 kJ/m²) with a scratch-resistant coating (Mohs hardness ≥5H), resisting damage from flying stones or minor collisions. The lens is sealed to the housing with a nitrile rubber gasket, preventing water and dust intrusion even during 30 minutes of 1m-deep water immersion. The wiring connector is also sealed with a silicone boot, blocking moisture from entering the electrical system. The lamp operates reliably across a wide temperature range (-40°C to 85°C), maintaining performance in frigid winter nights or hot summer afternoons—ideal for Kinland trucks operating in diverse climates, from northern snowfields to southern coastal areas

To safeguard the Kinland’s electrical system and the lamp itself from damage, the assembly integrates a multi-layer protection circuit. A built-in overvoltage protector cuts off power when the system voltage exceeds 16V (e.g., due to alternator faults), preventing LED burnout or circuit damage. Reverse polarity protection prevents short circuits if the wiring is connected incorrectly during installation—avoiding damage to the truck’s fuse box or wiring harness. The circuit also includes a current-limiting resistor that stabilizes power input, ensuring consistent light output even when the battery voltage fluctuates (e.g., during cold starts or when using high-power devices like air compressors). These safety features meet ISO 16750 automotive electrical standards, ensuring reliable operation in the Kinland’s complex electrical environment

Designed for easy replacement by fleet technicians or DIY owners, the position lamp simplifies installation with user-friendly features. The mounting kit includes 2 stainless steel M4×12mm screws (rust-resistant for snowy/coastal regions) that can be tightened with a standard Phillips screwdriver in 10–15 minutes. The 2-pin connector is plug-and-play, matching the Kinland’s factory wiring harness—no cutting, soldering, or adapters required. Aesthetically, the lamp features a factory-matched finish (matte black housing with clear lens) that blends seamlessly with the Kinland’s body design, maintaining the truck’s professional appearance for fleet operations. Each unit undergoes 100% light output testing, waterproof verification, and electrical performance checks, backed by a 24-month warranty against defects (e.g., LED failure, water leakage, housing cracking)
