Dongfeng GX cab top light assembly 3714150-C6202

The assembly integrates three core functions in one unit: position light, warning light, and roof marker light (consistent with Dongfeng GX’s functional configuration). The position light emits soft white light (color temperature: 5000K-6000K) for nighttime vehicle identification; the warning light features amber flashing mode (frequency: 1.5-2Hz) for hazard alerts; the roof marker light (red/white, per regulatory requirements) enhances visibility for large vehicles. All functions are controlled via the vehicle’s original switch panel, with no additional controllers needed—ensuring consistent operational logic with the factory system

Equipped with high-brightness SMD 2835 LEDs (12-16 LEDs total), the assembly delivers superior illumination: position light luminous flux ≥150lm, warning light ≥300lm, and roof marker light ≥80lm—meeting national automotive light standards (GB 4785). The optical lens adopts a frosted PC material with a uniform light distribution design, avoiding glare to oncoming vehicles while ensuring a visible range of up to 200 meters at night. The LEDs have a service life of ≥50,000 hours (10 times longer than halogen bulbs) and low power consumption (total working current ≤1.2A at 12V), reducing vehicle battery load

The assembly features a fully sealed structure with IP67 waterproof and dustproof rating. The housing is made of high-impact ABS plastic (surface hardness: ≥HB) with anti-UV coating, resisting fading, cracking, or deformation under long-term sunlight exposure (-40°C to 80°C operating temperature range). The lens is sealed to the housing with high-temperature-resistant silicone gaskets, and the wire connector is equipped with a rubber O-ring—preventing water, dust, or road salt from entering the internal circuit. It passes 48-hour salt spray tests and 1000-hour high-temperature aging tests, ensuring reliable performance in harsh environments

The assembly adopts a bolt-fixed and snap-on dual-installation design: it first snaps into the cab top’s positioning pins for quick alignment, then is secured with 4 M5 stainless steel bolts (matching original thread specifications). The wire harness uses a plug-and-play connector—simply insert it into the vehicle’s original socket without crimping or soldering. The entire installation process takes 15-20 minutes with only a Phillips screwdriver, saving 50% of time compared to universal top lights. The mounting holes are precisely calibrated (error ≤0.3mm), ensuring a tight fit to avoid vibration-induced noise during driving
