Dongfeng Kinalnd independent main trailer truck parts Flasher assembly 3735015-C0101

Built to handle the high electrical demands of independent main trailers, this flasher assembly features a robust electronic control module (ECM) that delivers consistent flashing frequency (60-120 flashes per minute, compliant with ISO 15500 standards). It supports a maximum load of 20A, capable of powering multiple turn signal and hazard light bulbs (up to 8 bulbs total) without overheating or voltage drop. The ECM includes overload protection: if a bulb burns out or a circuit shorts, it automatically adjusts the flashing frequency to trigger a “fast flash” warning—alerting the driver to the fault. Unlike mechanical flashers prone to wear, its solid-state design eliminates moving parts, ensuring stable performance across voltage fluctuations (20V-28V) common in heavy-duty truck electrical systems. This reliability is critical for trailer safety, as consistent turn/hazard signals prevent rear-end collisions or lane-change accidents during long-haul transportation

Engineered for the tough operating conditions of independent main trailers, the assembly features a rugged housing and protective design to resist environmental damage. The outer casing is made of impact-resistant ABS plastic with a UV-stabilized coating, preventing cracking, fading, or deformation under extreme temperatures (-40℃ to 85℃)—suitable for both freezing winter roads and hot summer highways. The wiring connector is sealed with a rubber O-ring, achieving an IP67 waterproof rating that blocks water, dust, and road salt from entering the internal circuits. This prevents short circuits or corrosion caused by heavy rain, snow, or muddy conditions. Additionally, the internal circuit board is coated with a moisture-proof conformal layer, ensuring stable performance even in high-humidity environments (e.g., coastal areas or rainy seasons). These features extend the assembly’s service life to over 100,000 kilometers, reducing replacement frequency for trailer operators

The 3735015-C0101 flasher assembly meets strict safety and performance standards for heavy-duty trailers, including China’s GB 4785 (automotive lighting and light-signaling devices) and international ECE R65 (heavy vehicle safety) regulations. It undergoes rigorous testing to verify reliability: 1,000-hour continuous operation tests to ensure no overheating, 500-cycle temperature shock tests (-40℃ to 85℃) to check structural stability, and electromagnetic compatibility (EMC) tests to prevent interference with the trailer’s GPS, radar, or other electronic systems. The assembly’s flashing frequency and signal consistency are calibrated at the factory to ensure visibility from a distance of 200 meters—critical for alerting other vehicles to the trailer’s movements on highways. By complying with global standards, it ensures Dongfeng Kinland independent main trailers meet road safety requirements in domestic and international markets

Designed for efficiency, the flasher assembly enables quick installation and hassle-free maintenance—critical for commercial trailer operators aiming to reduce downtime. It uses a bolt-on mounting design: the assembly is secured to the trailer’s existing flasher bracket with 2 standard M5 screws (included in the package), and the wiring connector is a plug-and-play type that mates directly with the trailer’s harness. No specialized tools or electrical expertise are needed; a basic screwdriver and 10 minutes are sufficient to complete replacement. For maintenance, the assembly’s transparent housing allows visual inspection of the internal circuit board (e.g., checking for corrosion or loose connections) without disassembly. If a fault occurs, the “fast flash” warning feature simplifies troubleshooting by immediately indicating bulb or wiring issues. This user-friendly design reduces repair time and labor costs, ensuring Dongfeng Kinland independent main trailers return to service quickly
