Dongfeng VR Front left turn signal assembly 3726010-C1200

Engineered for maximum conspicuity, this front left turn signal assembly emits a bright, standard amber light (wavelength 585-595 nm)—the optimal color for human eye recognition, ensuring other road users can quickly detect turning intentions even in low-light or adverse weather conditions. The assembly uses high-performance LED chips (12V/8W) that deliver a luminous flux of ≥300 lm, providing consistent brightness across a 160° horizontal visibility angle—covering the front and side areas of the truck to alert both oncoming vehicles and nearby pedestrians/cyclists. The LED chips feature instant activation (<0.05s response time), which is 3x faster than traditional incandescent bulbs, giving other drivers an extra 0.5-1 second of reaction time—critical for preventing collisions during lane changes or turns, especially in high-traffic urban or highway environments

Built to withstand the harsh operating conditions of commercial trucks, the 3726010-C1200 assembly features a dual-layer protection design: a high-impact polycarbonate (PC) lens and a reinforced ABS plastic housing. The PC lens is treated with a scratch-resistant coating (hardness rating ≥HRC 2H) and UV stabilizers, preventing yellowing, cracking, or surface damage even after 5,000+ hours of exposure to sunlight, road debris, stone impacts, or minor collisions. The ABS housing is corrosion-resistant and lightweight, reducing the overall load on the truck’s front end while maintaining structural integrity—capable of withstanding vibrations (up to 50 Hz) common in heavy-duty truck operation without component loosening. Both materials are tested to endure extreme temperature ranges (-40°C to 85°C), performing reliably in freezing winter climates or hot desert environments

To ensure consistent performance in diverse weather conditions, the assembly holds an IP67 ingress protection rating—providing complete protection against dust ingress and temporary submersion in water (up to 1 meter for 30 minutes). The lens and housing are sealed with a high-quality nitrile rubber (NBR) gasket that creates a tight, leak-proof seal, preventing rain, snow, road splashes, or dust from entering the internal electrical components. The wiring connector is also equipped with a waterproof rubber boot that secures the connection and blocks moisture, eliminating the risk of internal short circuits or corrosion of the LED chips and circuit board. This all-weather design ensures the turn signal operates reliably in heavy rain, fog, snow, or dusty construction site environments—critical for commercial trucks that operate 24/7 across diverse geographic regions

Designed for efficiency, the 3726010-C1200 assembly supports quick, tool-free installation: it attaches to the truck’s front-left frame via pre-fitted snap-in clips and a single plug-and-play wiring connector that matches the vehicle’s original harness. This reduces installation time from 45+ minutes (for generic turn signals) to 10-15 minutes, lowering labor costs for fleet maintenance teams. The assembly’s modular design allows easy access to internal components—removing the rear access panel by hand enables inspection or replacement of the LED module (if needed) without disassembling the entire housing. The LED chips have an ultra-long lifespan of 60,000+ hours (equivalent to 6+ years of average truck use), minimizing replacement frequency, and the PC lens/ABS housing require only occasional cleaning with water to maintain light transmission efficiency. The assembly is marked with the part number, manufacturing date, and compliance certifications (ECE R6, GB 4785, DOT) for easy inventory tracking and regulatory verification
