Dongfeng VR truck parts Right front combination lamp assembly 3772020-C1201

Designed to consolidate three critical lighting functions in one compact unit, the assembly enhances visibility and simplifies maintenance for Dongfeng VR operators. The low/high beam uses a dual-filament LED bulb (24V, 55W) emitting 4,800 lumens of cool white light (6,000K) for low beam (180m range) and 7,200 lumens for high beam (280m range), meeting ECE R112 headlight safety standards. The turn signal features a 24V, 20W amber LED strip (3,000K) with a flash frequency of 60±5 cycles per minute, ensuring high conspicuity for oncoming traffic. The daytime running light (DRL) integrates a 24V, 15W white LED array (6,500K) that activates automatically with the ignition, reducing rear-end collision risks by 35% (per road safety data). Unlike separate single-function lamps, this integrated design reduces bumper space usage by 40% and eliminates redundant wiring

All light sources in the assembly use premium SMD 5730 LED chips with a luminous efficiency of 125 lumens per watt—consuming 70% less power than traditional halogen bulbs (alleviating load on the truck’s alternator). The LEDs have a lifespan of 60,000+ hours (25x longer than halogens), eliminating frequent bulb replacements for fleet operators (equivalent to 8 years of daily use). A built-in aluminum heat sink (integrated into the lamp’s rear housing) dissipates heat at 18W/°C, keeping LED temperatures below 72°C to prevent lumen depreciation—maintaining 92% of initial brightness even after 15,000 hours of use. Unlike low-quality LEDs that dim or flicker in extreme temperatures, this premium design ensures consistent performance in -45°C (cold starts) to 95°C (engine bay heat)

Engineered to withstand the harsh operating environment of trucks (exposure to rain, dust, road debris, and vibration), the assembly features robust protection. The housing is made of high-grade PC (polycarbonate) plastic with a scratch-resistant coating (4H pencil hardness) that tolerates temperature extremes 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 (120kPa) and 12 hours of dust exposure without performance issues. The lens is 5mm-thick tempered glass that resists impact from stones or branches (enduring 1.8kg weight drops from 1m 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: 4 M6×20mm stainless steel bolts, lock washers, and a foam gasket that reduces vibration transfer to the bumper. Installation takes 20–25 minutes: remove the old lamp by unscrewing the mounting bolts, disconnect the 8-pin connector, align the new assembly with the bumper’s reference marks, secure the bolts (torque to 22 N·m), and plug in the connector. The tempered glass lens is removable (via hidden clips) for easy cleaning if covered in mud or bug splatters—no tools required. Each unit undergoes brightness testing (beam pattern, intensity), waterproof verification, and impact trials, backed by a 24-month warranty against defects (e.g., LED failure, housing cracking, water leakage)
