Dongfeng VR truck parts Left front fog lamp assembly 3732020-C1100

Designed to cut through fog, rain, dust, and snow (the most challenging low-visibility scenarios for trucks), the fog lamp uses a high-performance amber LED bulb (24V, 25W) emitting 2,750 lumens of warm amber light (3,000K color temperature). This wavelength minimizes light scattering in water droplets or dust particles—delivering a 38% wider and 29% longer visible range (up to 78m) compared to white fog lamps, ensuring other road users and obstacles are detected earlier. The lamp’s reflector is precision-molded with a multi-faceted design that concentrates light into a wide, flat beam pattern—avoiding glare for oncoming drivers (meeting ECE R19 fog lamp safety standards). Unlike halogen fog lamps that dim over time, this LED design maintains consistent brightness, critical for night driving in heavy fog or rural areas with limited street lighting

Engineered to withstand the harsh operating environment of trucks (exposure to water, road debris, and temperature extremes), the fog lamp features robust protection. The housing is made of impact-resistant PC (polycarbonate) plastic (UL94 V-0 flame-retardant rating) that tolerates temperatures from -45°C (cold starts) to 90°C (engine bay heat) without cracking or warping. 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 (100kPa) and 10 hours of dust exposure without performance issues. The lens is 4mm-thick tempered glass that resists impact from stones or branches (enduring 1.2kg weight drops from 0.8m with no damage). Unlike plastic-lensed fog lamps that scratch or shatter easily, this design ensures durability in all weather and road conditions

The fog lamp’s core light source uses premium SMD 5630 LED chips with a luminous efficiency of 110 lumens per watt—consuming 60% less power than traditional halogen fog lamps (reducing load on the truck’s alternator and battery). The LEDs have an industry-leading lifespan of 50,000+ hours (20x longer than halogens), eliminating frequent bulb replacements for fleet operators (equivalent to 6+ years of daily use). A built-in aluminum heat sink (integrated into the lamp’s rear housing) dissipates heat at 11.8W/°C, keeping LED temperatures below 70°C to prevent lumen depreciation—maintaining 89% of initial brightness even after 12,000 hours of use. Unlike low-quality LEDs that flicker or fail within 1–2 years, this premium design ensures reliable performance, reducing maintenance costs and downtime

Designed for hassle-free replacement by technicians or DIY owners, the fog lamp simplifies installation and upkeep. It includes all necessary hardware: 2 M6×16mm stainless steel bolts, lock washers, and a foam gasket that reduces vibration transfer to the bumper. Installation takes 15–20 minutes: remove the old lamp by unscrewing the mounting bolts, disconnect the 3-pin connector, align the new assembly with the bumper’s fog lamp cavity, secure the bolts (torque to 18 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 an 18-month warranty against defects (e.g., LED failure, housing cracking, water leakage)
