Dongfeng VR Sleeper Reading Light Assembly 3714180-C1100

Engineered to enhance in-cab comfort, this reading light assembly features a dimmable LED light source and 360° adjustable lamp head, tailored to meet drivers’ personalized reading needs. The high-quality SMD LED chips emit warm white light (3000K-3500K color temperature)—a range proven to reduce eye strain during extended reading sessions, unlike harsh cool-white lights that cause visual fatigue. The dimming function (adjustable from 10% to 100% brightness via a built-in touch switch) allows drivers to adjust light intensity based on ambient conditions (e.g., dim for night reading, bright for document checking). Additionally, the lamp head can be rotated 360° horizontally and tilted 180° vertically, enabling precise light focusing on books, tablets, or documents without illuminating the entire sleeper cab—avoiding disturbing co-drivers or affecting sleep quality

Built to withstand the unique conditions of truck sleeper cabs (including vibration, temperature fluctuations, and occasional impact), the 3714180-C1100 assembly features a rugged yet lightweight design. The lamp housing is made of flame-retardant ABS plastic (compliant with UL94 V-0 standards), which resists scratches, impacts, and deformation—even when exposed to accidental bumps from bedding or personal items. The LED lens is crafted from high-transmittance polycarbonate (PC) that blocks UV radiation, preventing yellowing or cracking over time (tested to maintain clarity after 10,000+ hours of use). The assembly also endures extreme temperature ranges (-30°C to 70°C), performing reliably in cold winter cab conditions or hot summer environments without light flickering or component failure

This reading light assembly prioritizes energy efficiency and longevity, leveraging advanced LED technology to reduce power consumption while extending service life. The SMD LED chips operate at just 2-3W (far lower than traditional incandescent reading lights, which consume 10-15W), minimizing drain on the truck’s battery—critical for drivers who use the light when the engine is off. Despite its low power use, the LED delivers a luminous flux of 150-200 lm, providing sufficient brightness for reading at a distance of 30-50 cm. The LED components have an ultra-long lifespan of 50,000+ hours (equivalent to 5+ years of daily 3-hour use), eliminating the need for frequent bulb replacements—reducing maintenance costs and ensuring reliable performance for long-haul truck operations

Designed for maximum convenience, the 3714180-C1100 assembly supports quick, tool-free installation in Dongfeng VR sleeper cabs. It mounts via two pre-fitted snap-in clips or self-tapping screws (included in the package) that align with the cab’s original installation points, allowing drivers or maintenance teams to complete setup in 5-10 minutes. The assembly’s control interface is intuitive: a built-in touch-sensitive switch (located on the lamp housing) enables one-touch on/off and dimming, eliminating the need for bulky external switches. For added safety, the light features an overcurrent protection circuit that automatically shuts off power if electrical current exceeds 0.3A, preventing damage to the truck’s electrical system. The assembly is also marked with the part number and voltage rating for easy identification, simplifying inventory management for fleet operators
