Dongfeng KR truck parts Right turn signal assembly 3726220-C5101

At the core of the assembly are high-performance LED bulbs that deliver exceptional signal visibility in all weather conditions. Each bulb emits 800 lumens of amber light (compliant with ECE R65 and SAE J592 standards) with a 120° horizontal beam angle—ensuring the turn signal is visible to other drivers from up to 300 meters away, even in heavy rain or fog. The LEDs have a fast response time (≤10ms), activating 0.5 seconds quicker than incandescent bulbs to give following vehicles more time to react. With a lifespan of 50,000+ hours (20x longer than incandescent bulbs), they eliminate frequent bulb replacement, reducing maintenance costs for fleet operators. Unlike dim or short-lived bulbs that compromise safety, this LED design ensures reliable signal transmission for 5+ years of daily use

The assembly’s housing is crafted from high-grade PC (polycarbonate) plastic with a scratch-resistant coating, engineered to withstand minor impacts and harsh road conditions. The PC material tolerates temperature extremes from -40°C to 85°C without cracking or warping, and resists damage from road debris (e.g., stones, branches) — enduring 1kg weight drops from 0.5m with only minor surface scratches. The housing’s curved design redirects impact force away from the LED bulbs, protecting internal components from damage. Unlike brittle ABS plastic housings that shatter on impact, this PC construction maintains structural integrity, ensuring the turn signal functions properly even after minor collisions or rough handling

Designed to prevent water and dust from damaging internal electrical components, the assembly meets IP67 ingress protection standards. All seams between the housing and lens are sealed with EPDM rubber gaskets (resistant to ozone and temperature changes) that create an airtight, watertight barrier. The electrical connector is equipped with a rubber O-ring seal that blocks moisture from entering the wiring interface, preventing short circuits. In testing, the assembly withstands 30 minutes of high-pressure water spraying (80kPa) from all angles and 8 hours of dust exposure without performance issues—making it reliable in heavy rain, snow, or dusty construction site environments. Unlike non-waterproof assemblies that fail after exposure to moisture, this design ensures long-term electrical safety and functionality

Engineered for easy replacement by technicians or DIY owners, the assembly features a user-friendly design and plug-and-play functionality. It includes all necessary mounting hardware: 2 OEM-matched plastic clips and 1 self-tapping screw that secure the housing to the fender without drilling. Installation takes 10–15 minutes: align the assembly with the fender’s mounting points, snap the clips into place, fasten the screw, and plug the 3-pin connector into the truck’s original wiring harness—no wiring modifications or soldering required. The lens is removable (via hidden clips) for easy cleaning or replacement if scratched, and the LED bulbs are integrated into the housing (no separate bulb installation needed). Each unit undergoes brightness testing, waterproof verification, and impact trials, backed by a 12-month warranty against defects (e.g., LED failure, housing cracking, water leakage)
