Dongfeng Xinjiang X7 truck spare parts Halogen left front combination lamp N230H3772011

Built with left-specific light distribution, this combination lamp integrates high/low beam, turn signal, and position light functions using premium 12V halogen bulbs, tailored for left-front visual demands. The high beam (H1 bulb, 100W) delivers a concentrated beam with 15,000 lux intensity at 10m and 150m maximum range, enhancing visibility of left-side road edges and obstacles on unlit highways. The low beam (H7 bulb, 55W) features an asymmetric cutoff line—lower on the right to avoid dazzling oncoming traffic and higher on the left to illuminate curbs and lane markers, with 30m horizontal coverage. The amber turn signal (PY21W bulb, 800cd brightness, 1.5Hz flash frequency) and red position light (T10 bulb, 5W) meet ECE R69 standards, ensuring the truck’s left-side presence is clearly visible in all conditions

Engineered to withstand the harsh impacts of commercial truck operation, the lamp features a rugged protective design. The lens is made of impact-resistant polycarbonate (PC) with a hard coating (Mohs hardness ≥5), capable of enduring 10J impact (equivalent to a 1kg stone at 50km/h) without cracking—critical for left-front exposure to road debris. The die-cast aluminum (ADC12) housing dissipates heat 30% more efficiently than plastic, preventing bulb overheating and extending service life by 50%. A durable silicone gasket seals the lens and housing, achieving IP67 waterproof rating to block rain, snow, and car wash water from intruding into internal circuits. Reinforced steel inserts in the mounting brackets resist vibration-induced loosening, ensuring stability during off-road or construction site use

Designed for long-term reliability in diverse climates, the combination lamp exhibits exceptional resistance to environmental wear. The PC lens’s anti-UV coating maintains ≥85% light transmittance after 2000-hour QUV testing, preventing yellowing and ensuring consistent illumination for over 5 years. The aluminum housing undergoes electrophoretic and powder coating, passing 1000-hour salt spray testing (ASTM B117) with no corrosion—suitable for coastal areas and snowy regions with deicing salt. Internal wiring uses high-temperature Teflon insulation (150℃ resistance) to avoid melting from bulb heat. The lamp operates stably in extreme temperatures from -40℃ (northeast China winters) to 85℃ (desert regions), with no performance loss during repeated thermal cycles

Optimized for efficient fleet maintenance, the lamp features a user-friendly plug-and-play design tailored for left-front replacement. It comes pre-assembled with all bulbs (H1, H7, PY21W, T10) and a pre-wired harness, eliminating separate bulb installation. The 10-pin connector’s keyed design prevents reverse connection, ensuring correct electrical pairing with the X7’s left-front wiring. Installation takes three simple steps: remove the original lamp’s M6 bolts with a socket wrench, disconnect the old harness, and secure the new lamp using included galvanized M6×20 bolts (torque: 8-10N·m). Clear labeling (“LEFT FRONT” and bulb type markers) avoids installation errors. A single technician can complete replacement in 15 minutes or less, significantly reducing truck downtime and maintenance costs for fleet operators
