380904902 380904903 XCMG GR2605 motor grader lampshade

The XCMG GR2605 grader 380904902/380904903 lampshade (left and right lamp covers) is the core protective and optical optimization component of the entire machine’s headlight. It features a symmetrical design (one on each side) to match the engine hood, manufactured strictly according to XCMG’s original design standards and engineering machinery lighting protection specifications. Specifically designed for the GR2605 grader’s headlight system, it is suitable for harsh outdoor working environments such as highway construction, airport construction, mining operations, and large-scale earthmoving, characterized by strong light, high dust, strong vibration, and fluctuating high and low temperatures. As a “protective barrier and light optimizer” for the headlight, it resists impact from gravel, dust intrusion, and rain erosion, protecting the internal LED light source and circuitry from damage. Its optical optimization design ensures uniform light diffusion, avoids glare, and guarantees clear visibility at night or in low-visibility conditions. It is a high-quality, symmetrical replacement part from the original manufacturer for aging or damaged lamp covers in the GR2605 grader’s lighting system.

These left and right lampshades are made of high-strength polycarbonate (PC) engineering plastic through a single injection molding process. The material has a melting point of up to 250℃ and maintains stable performance within a wide temperature range of -40℃ to 120℃. Its impact resistance is 30 times that of ordinary acrylic and 250 times that of glass, effectively resisting external impacts such as flying gravel and minor collisions during construction. It is not easily broken or deformed, and when broken, it will not shatter into sharp fragments, reducing the risk of injury. The lampshade surface undergoes special UV anti-aging and anti-glare diffusion treatment, achieving a light transmittance of up to 90%. This ensures both lighting brightness and even light diffusion, preventing direct glare from affecting the vision of operators and surrounding personnel. It also resists yellowing and aging caused by long-term sunlight exposure, maintaining stable light transmittance for 5-10 years.

The lamp cover features a contoured design precisely matched to the headlight body, with an integrated EPDM sealing ring on the edge. The gap between the cover and the lamp body is ≤0.05mm, achieving an IP65 protection rating. This completely prevents dust ingress and low-pressure water jets, effectively blocking rainwater, mud, and dust from entering the lamp body and preventing short circuits or light source damage. The outer surface of the lamp cover has a hydrophobic coating, allowing rainwater to quickly slide off, reducing water residue and ensuring clear illumination in rainy weather. The inner side features a reinforcing rib structure to enhance overall rigidity and aid in heat dissipation, extending the lifespan of the LED light source.

The product’s mounting clips and fixing holes precisely match the pre-drilled positions on the XCMG GR2605 original headlight assembly and engine hood. 380904902 corresponds to the left headlight, and 380904903 corresponds to the right headlight. Hole tolerances are controlled within ±0.03mm, and symmetry error is ≤0.1mm, maintaining consistency with the overall appearance of the unit. No additional modifications are required during installation. The headlights are securely fastened with both original clips and bolts, ensuring a tight and reliable fit. They remain stable and noiseless even under peak vibration conditions of 25g. Disassembly is convenient; simply loosen the clips and bolts for individual replacement, eliminating the need to disassemble the entire headlight assembly, resulting in high maintenance efficiency.
