Dongfeng KR truck parts Left front fog lamp and auxiliary high beam assembly 3732110-C5100

Designed to enhance visibility in diverse driving conditions, the assembly integrates two independent lighting functions in one compact unit. The fog lamp uses a wide-beam LED bulb (12V, 24W) that emits 2,200 lumens of warm white light (3,000K color temperature)—cutting through fog, rain, or snow to illuminate the road surface 5–10 meters ahead without glare for oncoming drivers (compliant with ECE R19 fog lamp standards). The auxiliary high beam features a narrow-beam LED bulb (12V, 36W) that delivers 3,500 lumens of cool white light (6,000K), extending high-beam coverage by 40% for rural or highway night driving—complementing the main headlights to reduce blind spots. Unlike separate fog lamps and auxiliary beams that require dual mounting, this integrated design saves bumper space and simplifies wiring, reducing installation complexity by 50%

Both the fog lamp and auxiliary high beam use high-quality SMD 5050 LED chips with a luminous efficiency of 110 lumens per watt—ensuring bright, energy-efficient lighting while consuming 60% less power than traditional halogen bulbs (reducing load on the truck’s electrical system). The LEDs have a lifespan of 50,000+ hours (20x longer than halogens), eliminating frequent bulb replacement for fleet operators. A built-in aluminum heat sink (integrated into the lamp housing) dissipates heat quickly, keeping LED temperatures below 70°C to prevent lumen depreciation—maintaining 90% of initial brightness even after 10,000 hours of use. Unlike low-quality LEDs that dim or fail within 1 year, this premium LED design ensures reliable performance for 5+ years of daily use

Engineered to withstand harsh automotive environments—water, dust, and road debris—the assembly features robust protection. The lamp housing is made of high-grade PC (polycarbonate) plastic with a scratch-resistant coating that tolerates temperature extremes from -40°C to 85°C without cracking. All seams between the housing and lens are sealed with EPDM rubber gaskets (resistant to ozone and aging), meeting IP67 ingress protection standards—withstanding 30 minutes of high-pressure water spraying (80kPa) and 8 hours of dust exposure without performance issues. The lens is 3mm-thick tempered glass that resists impact from stones or branches (enduring 1kg weight drops from 0.5m with no damage). Unlike plastic-lensed assemblies that scratch or shatter easily, this design ensures durability in rain, snow, or off-road conditions

Designed for hassle-free replacement by technicians or DIY owners, the assembly simplifies installation and upkeep. It includes all necessary hardware: 2 OEM-matched plastic clips and 1 self-tapping screw that secure the housing to the bumper without drilling. Installation takes 15–20 minutes: align the assembly with the bumper’s mounting points, snap the clips into place, fasten the screw, and plug the 4-pin connector into the original wiring harness—no wiring modifications needed. The tempered glass lens is removable (via hidden clips) for easy cleaning if covered in mud or insects, and the LEDs are integrated into the housing (no separate bulb replacement required). Each unit undergoes brightness testing (fog beam pattern, high beam range), waterproof verification, and impact trials, backed by a 12-month warranty against defects (e.g., LED failure, housing cracking, water leakage)
