Dongfeng KL truck parts Cigarette lighter assembly 3725010-C3300

Built to serve both traditional ignition and modern power needs, this assembly integrates dual functionality for Dongfeng KL drivers. The core ignition element is a nickel-chromium alloy coil that heats to 600-700℃ within 8-10 seconds, ensuring reliable cigarette lighting. When not used for ignition, the assembly acts as a 12V power outlet (15A max) compatible with various driver devices: mobile phone chargers, GPS navigators, dash cams, and portable heaters. The socket features a standard SAE J563 interface, supporting most 12V automotive accessories. A spring-loaded eject mechanism automatically pushes the lighter out when heated to the optimal temperature, preventing overheating and reducing the risk of driver distraction. This dual design balances practicality for smoking drivers and utility for all operators, enhancing cab convenience

Engineered as a safety-focused component, the 3725010-C3300 assembly integrates multiple protective mechanisms to prevent electrical hazards. A built-in thermal fuse (15A rating) automatically cuts off power if current exceeds the safe limit, avoiding wire overheating and fire risks caused by short circuits (e.g., faulty chargers). The socket housing uses flame-retardant PBT plastic (UL94 V-0 grade) that resists ignition and melts only at temperatures above 250℃. A silicone insulation ring between the metal core and plastic housing prevents current leakage, with an insulation resistance of ≥100MΩ (DC 500V) to ensure operator safety. The eject mechanism also serves as a fail-safe: if the lighter is forgotten, it cools down quickly after ejection, reducing the risk of burns or interior damage

Optimized to withstand the rigorous conditions of truck cab use, the assembly features a rugged and wear-resistant structure. The ignition coil is made of high-purity nickel-chromium alloy (Cr20Ni80) with excellent thermal stability, enduring 10,000+ heating cycles without breakage. The socket’s metal contacts are tin-plated copper (5μm thickness) that resists corrosion and ensures low contact resistance (≤0.05Ω), maintaining stable power transmission even after repeated plugging/unplugging (5,000+ cycles). The outer bezel is made of brushed stainless steel (304 grade) that resists scratches and fingerprints, retaining a clean appearance in dusty or greasy cab environments. The assembly operates stably within a temperature range of -40℃ to 85℃, adapting to frigid northern winters and sun-exposed dashboards

This cigarette lighter assembly is designed for efficient installation and long-term cost savings for Dongfeng KL operators. Its snap-in mounting design allows a single technician to complete replacement in 15 minutes using only a flathead screwdriver—no specialized tools required. The OE-compatible connector ensures a secure electrical connection, avoiding the loose contacts that cause device charging failures (a common issue with aftermarket units, leading to $100+ in unnecessary adapter replacements). The high-durability components extend the assembly’s service life to ≥200,000km—four times that of cheap non-OE alternatives—reducing replacement frequency. By supporting device charging, it eliminates the need for additional power inverters (costing $50-100), lowering overall cab equipment expenses. Backed by a 1-year/150,000km Dongfeng warranty, it provides reliable performance and predictable maintenance costs for fleet operations
