Dongfeng KL truck parts Left rear combination taillight 3773010-T0500

This left rear combination taillight (Part No. 3773010-T0500) is exclusively engineered for Dongfeng KL truck models, developed via 3D laser scanning of the original vehicle’s rear left-side frame bracket and body contour. It adheres to strict OEM dimensional tolerances: overall size (420mm×180mm×100mm), mounting hole spacing (320mm center-to-center), and electrical connector pinout (6-pin OEM standard)—all within ±0.3mm of factory specifications. Unlike universal combination taillights that require drilling or adapter plates, it directly bolts to the truck’s pre-existing rear frame bracket and plugs into the original wiring harness. This precise fit ensures seamless alignment with the cab’s rear contour, avoids gaps that trap water or debris, and maintains the truck’s factory aesthetic—critical for fleet uniformity and compliance with vehicle appearance regulations

PRODUCT DESCRIPTION

01

Multi-Functional Lighting Integration for Comprehensive Signaling​

Designed as an all-in-one rear lighting solution, the taillight integrates four core functions: left turn signal, brake light, reverse light, and parking light—eliminating the need for separate single-function lamps. The left turn signal uses 8 amber SMD LEDs (300 lumens, 6000K) with a flash rate of 60–120 flashes per minute; the brake light features 12 high-brightness red LEDs (450 lumens) that intensify by 50% when the brake is applied; the reverse light includes 6 white LEDs (500 lumens) for clear visibility during backing; and the parking light uses 4 low-power red LEDs (50 lumens) for nighttime presence. This integration simplifies wiring (single 6-pin connector) and reduces component redundancy, unlike scattered lamps that increase failure risks and complicate maintenance

02

High-Visibility Design for All-Weather Safety​

Engineered to maximize visibility for other road users in all conditions, the taillight features optimized light dispersion and brightness. The red/amber/white lenses are made of frosted polycarbonate with a prismatic inner structure that diffuses light evenly (no hotspots) and extends visibility to 800+ meters in daylight, fog, or heavy rain. The brake light’s 450-lumen output meets ECE R108 and FMVSS 108 standards—300% brighter than incandescent brake lights—ensuring rapid recognition by following vehicles (critical for preventing rear-end collisions). The reverse light’s 500 lumens illuminate a 3-meter-wide area behind the truck, enhancing safety during nighttime or low-light backing. Unlike dim, unevenly lit lamps, this high-visibility design reduces accident risks by 40% in adverse weather

03

Rugged & Weather-Resistant Construction​

Built to withstand the harsh conditions of commercial truck use—including road debris impact, vibration, and extreme weather—the taillight features a durable structure. The housing is made of impact-resistant ABS plastic (UL94 V-0 flame-retardant rating) that resists cracks from minor collisions (e.g., hitting curbs or pallets) and maintains rigidity in temperatures ranging from -40°C to 90°C. The lens is a 4mm-thick polycarbonate sheet with a scratch-resistant coating (resisting damage from truck washes or gravel) and UV stabilizers that prevent fading or yellowing for 5+ years. The taillight meets IP67 waterproof/dustproof standards: a rubber O-ring seals the housing-lens junction, and a sealed 6-pin connector blocks moisture intrusion—avoiding short circuits from rain, snow, or road salt

04

Easy Installation & Compliance with Global Standards​

Designed for efficient replacement by fleet technicians or DIY owners, the taillight simplifies installation with user-friendly features. It includes 6 OEM-matched bolts (M6×20mm) that fit the truck’s existing rear frame holes, requiring no drilling. The 6-pin electrical connector is keyed and color-coded to match Dongfeng KL’s wiring harness, eliminating reverse polarity or miswiring (which damages lamps or the truck’s electrical system). Installation takes 25–30 minutes with standard hand tools (e.g., socket wrench), as the taillight aligns perfectly with the rear frame’s reference marks. The combination taillight complies with global safety regulations (ECE R65 for lighting performance, ISO 14080 for environmental durability) and is certified for use in major markets (EU, North America, Asia). Backed by a 24-month warranty against manufacturing defects (e.g., LED failure, lens cracking, waterproof seal damage), it provides Dongfeng KL truck owners with reliable rear signaling and long-term safety

TECHNICAL SUPPORT
