Dongfeng DFAC captain truck parts Left rear combination lamp assembly 37QC9-73010-AE

Built as a comprehensive rear lighting solution, this combination lamp integrates four core functions: brake light, turn signal, reverse light, and position light—eliminating the need for separate single-function lamps. The brake light uses a 10W high-brightness LED chip with a luminous flux of 800lm, ensuring it is visible from 500m away to warn following vehicles. The amber turn signal (8W LED) features a 50Hz flash frequency, meeting GB 4785-2019 standards for clear directional indication. The reverse light (12W LED) provides 1200lm illumination, brightening the rear area by 30㎡ to assist safe reversing. The red position light (3W LED) operates continuously to mark the truck’s outline at night

Engineered to endure the harsh operating environments of urban and rural transportation, the lamp assembly achieves an IP67 protection rating. The housing is made of impact-resistant PC/ABS alloy (UL94 V-0 flame-retardant rating) that resists cracking from stone impacts or minor collisions. The lens uses a scratch-resistant PMMA material with an anti-fog coating, ensuring clear light transmission even in heavy rain or fog. The 7-pin connector is sealed with a nitrile rubber gasket, preventing water and dust intrusion into the internal circuit. It undergoes 30-minute submersion testing at 1m depth and 500-hour dust chamber testing, ensuring reliable performance in rainy, dusty, or muddy conditions

The combination lamp adopts advanced LED technology to optimize energy efficiency and durability. Compared to traditional incandescent bulbs, the LED chips consume 70% less power (total power ≤33W) while providing 3 times brighter illumination. This reduces the truck’s battery load, extending battery life by 20% and avoiding dead battery issues caused by long-term lighting. The LED chips have a lifespan of ≥50,000 hours—equivalent to 8 years of typical use—far exceeding the 1,000-hour lifespan of incandescent bulbs. The solid-state LED design has no filament to break, ensuring stable operation even under 15g vibration loads (ISO 16750-3)

Designed for efficient installation and long-term cost savings, the lamp assembly features a user-friendly structure. It comes with 4 pre-aligned M6 mounting bolts that match the truck’s rear chassis holes, allowing a single technician to complete replacement in 20 minutes—50% faster than non-OE lamps. The 7-pin connector uses a snap-lock design for plug-and-play connection to the wiring harness, with polarity protection to prevent damage from reverse connection. The long LED lifespan and weatherproof design reduce replacement frequency by 80%, lowering maintenance costs for fleet managers and individual truck owners. Backed by a 2-year/150,000km warranty, it ensures reliable performance for urban delivery and long-distance transportation
