Dongfeng VR Rear combination lamp 3773020-KC100

This rear combination lamp integrates four critical safety functions in a single, compact unit: red tail light, high-brightness brake light, amber turn signal, and reverse light—covering all mandatory rear lighting requirements for commercial vehicles. The tail light uses energy-efficient LED chips (12V/5W) to emit a steady red glow with a 180° visibility angle, ensuring the vehicle is visible to following traffic even in low-light conditions. The brake light, with enhanced LED intensity (12V/10W), activates instantly (response time <0.1s) when the brake pedal is pressed, providing longer reaction time for rear vehicles. The amber turn signal (12V/8W) features a fast-flash mode (60-120 flashes per minute) compliant with international safety standards, while the reverse light (12V/15W) delivers a wide, white beam to illuminate the area behind the truck during backing-up, reducing collision risks with obstacles or pedestrians

Constructed to withstand the rigorous conditions of commercial truck use, the 3773020-KC100 lamp features a dual-layer protection design: a high-impact polycarbonate (PC) lens and a reinforced ABS plastic housing. The PC lens is scratch-resistant (hardness rating ≥HRC 2H) and UV-stabilized, preventing yellowing, cracking, or fading even after 5,000+ hours of exposure to sunlight, rain, or road debris. The ABS housing is corrosion-proof and impact-resistant, capable of withstanding accidental collisions with small obstacles (e.g., curbs, loading docks) without structural damage. Both materials are tested to endure extreme temperature ranges (-40°C to 85°C)—performing reliably in freezing winter climates or hot desert environments—and meet IP67 waterproof standards, ensuring complete protection against dust ingress and temporary submersion in water (up to 1m for 30 minutes), eliminating internal short circuits caused by rain or road splashes

The lamp’s optical system is engineered to meet global safety regulations, including ECE R7, GB 4785, and FMVSS 108, ensuring compliance in domestic and international markets. The tail and brake lights use a multi-reflector design that distributes light evenly across the beam pattern, avoiding hotspots or dark areas that could reduce visibility. The brake light’s brightness (≥800 cd) is 3x higher than the tail light, creating a clear visual distinction between “driving” and “braking” states for rear drivers. The reverse light’s optical lens is designed to project a wide, flat beam (coverage width ≥2.5m at 5m distance) rather than a concentrated spot, maximizing visibility of the ground and obstacles behind the truck. Additionally, the lamp’s light color meets strict chromaticity standards: red (tail/brake) with a wavelength of 620-660nm, amber (turn signal) at 585-595nm, and white (reverse) at 5500-6500K—ensuring high recognizability in all weather conditions (fog, rain, snow)

Designed for ease of use, the 3773020-KC100 rear combination lamp supports quick, tool-free installation: it mounts directly to the truck’s rear frame via pre-installed snap-in clips and a single wiring harness plug that connects to the vehicle’s original electrical system (plug-and-play functionality). This reduces installation time from 60+ minutes (for generic lamps) to 15-20 minutes, lowering labor costs for fleet maintenance. The lamp’s modular design allows for easy bulb/LED replacement: the rear access panel can be removed by hand to access individual light components, eliminating the need to disassemble the entire housing. Furthermore, the LED components have a lifespan of 50,000+ hours (equivalent to 5+ years of average truck use), while the PC lens and ABS housing require no regular maintenance—only occasional cleaning with water—to maintain performance. The lamp is also marked with the part number, manufacturing date, and compliance certifications (e.g., ECE, CCC) for easy inventory tracking and regulatory verification
