Dongfeng KL truck parts Front reading light assembly 3714060-C3300

Equipped with two high-performance SMD LED chips, the assembly delivers bright, focused illumination ideal for in-cab reading and task lighting. Each LED emits 35 lumens of 6500K cool white light — a color temperature that reduces eye strain during extended use — with a beam angle of 120° to cover a 50cm × 30cm area (e.g., maps, documents, or control panels). The LEDs consume only 1.2W of power (far less than incandescent bulbs that use 10W+), minimizing drain on the truck’s battery during idle. Unlike traditional bulbs that burn out within 1,000 hours, these LEDs have a lifespan of 50,000+ hours, reducing replacement frequency and maintenance costs for fleet operators. The light output remains consistent over time, avoiding dimming that impairs visibility

Built to withstand the vibrations, temperature fluctuations, and occasional impacts of truck operation, the assembly features a rugged design. The housing is made of impact-resistant ABS plastic (UL94 V-0 flame-retardant rating) that resists cracks from bumps or tool drops. The lens is a clear polycarbonate sheet with a scratch-resistant coating, maintaining optical clarity even after repeated cleaning. Internally, components are secured with vibration-dampening gaskets that prevent loose connections or rattling during rough road conditions. The assembly operates reliably in temperatures ranging from -30°C to 70°C — ensuring functionality in extreme winter or summer conditions — and is resistant to dust and moisture (IP54 rating), protecting internal electronics from cab humidity or spills

Designed for intuitive use by drivers, the reading light includes two independent rocker switches (one for each LED) that allow precise control over illumination. The switches feature a tactile click mechanism for easy operation, even with gloves, and maintain their function through 10,000+ actuations. The assembly also supports dimming functionality when connected to the truck’s optional cabin control system, allowing drivers to adjust brightness from 10% to 100% to avoid glare during night driving. Unlike lights with single On/Off controls, this flexible design caters to various needs — from bright task lighting to subtle ambient illumination — enhancing driver comfort during long hauls

Engineered for straightforward replacement in repair shops or by fleet maintenance teams, the assembly simplifies installation with plug-and-play functionality. It uses the truck’s existing mounting screws (included) and connects via a 3-pin OEM-compatible connector that mates with the cab’s wiring harness — no cutting or splicing required. Installation takes 10–15 minutes with basic hand tools. The light complies with automotive safety standards (ECE R10 for electromagnetic compatibility, ISO 2575 for light output), ensuring it doesn’t interfere with the truck’s electronics or dazzle other drivers. Each unit undergoes rigorous testing: vibration resistance (20G acceleration), thermal cycling (-30°C to 70°C), and switch durability trials. Backed by a 12-month warranty against defects (e.g., LED failure, switch malfunction, or housing cracks), it provides Dongfeng KL truck owners with reliable in-cab lighting and long-term performance
