K1C Series 5202 LED Headlight Bulb for Cars and Trucks

Universal for Cars and Trucks

K1C Series 5202 is built as a practical headlight upgrade for a wide range of passenger vehicles and light-duty trucks that use the 5202 bulb type. The design focuses on straightforward compatibility for daily driving and commercial use, helping installers complete the job without complicated modifications. Polarity protection is included to reduce installation risk when connector orientation differs across vehicle platforms, so the bulb can be integrated more smoothly into real-world harness variations.

Powerful performance

This model uses four GC-7035 LED chips and is specified with a 360° beam angle target, supporting consistent light distribution when installed in suitable headlamp optics. Electrical operation is rated at DC 9–36V and the input current is 5.0±0.5A at 13.2V, matching common automotive electrical systems. Output is presented in two states to reflect real operating behavior over time. Initial power output is 68.14W per bulb with an initial measured output of 5948 lumens per bulb, while stable operation at 30 minutes is 61.68W per bulb and 5016 lumens per bulb. Color temperature is rated at 6500K with a ±500K tolerance for a crisp white beam appearance.

Heat Dissipation System

Thermal control is handled through a combined cooling architecture that uses dual copper heat pipes and an active fan system. Copper heat pipes are used to move heat away from the LED heat source efficiently and spread it into the aluminum structure, reducing localized hot spots during long runtimes. A silent fan supports airflow through the heat sink area to keep the thermal pathway effective when the vehicle is idling, moving slowly, or operating in warm ambient temperatures. This approach helps the bulb reach a steady operating point and maintain more consistent brightness across extended night driving.

Integrated Die-Casting Structure

The bulb body is engineered around a die-cast aluminum structure that supports both durability and heat capacity. High-brightness LED chips are mounted in a layout intended to work with headlamp optics while managing thermal load. The overall structure integrates the thermal components and mechanical support so the assembly remains stable in typical automotive vibration and temperature cycling. This 5202 version is specified with a non-adjustable chuck, which simplifies the mechanical structure and keeps alignment consistent with the intended installation orientation for the 5202 base type.

External Intelligent Driver

An external intelligent driver is used to regulate power delivery to the LEDs. Keeping the driver outside the main bulb body helps separate sensitive electronics from the hottest zone near the LED heat source. In operation, the driver manages current delivery so the transition from initial output to stable output is controlled and predictable, supporting consistent performance during real driving sessions rather than only short bench tests. The external layout also supports easier cable routing inside headlamp cavities where space can be limited.

Precise Cutoff and Road Coverage

The lighting concept emphasizes controlled road coverage with an anti-dazzle intent. A precise cutoff helps keep light directed where drivers need it, reducing stray glare that can affect oncoming traffic when the headlamp optics and aim are correct. Balanced road coverage improves forward visibility while maintaining usable spread for lane edges and roadside awareness. This makes the bulb suitable for drivers who want a clear, confident beam pattern for mixed city and highway conditions.

Low Beam and High Beam Performance

In real road use, low beam should prioritize a clean boundary and even foreground illumination, while high beam should extend reach down-road for earlier hazard recognition. The beam pattern visuals focus on a controlled low-beam shape and a concentrated high-beam distribution, supporting practical visibility gains without excessive scatter. When installed and aimed properly, this balance helps drivers maintain comfort in traffic while still delivering stronger down-road information when high beam is used.

Compliance

The product is marked for CE and RoHS compliance, supporting distribution needs in markets where these requirements are commonly requested during procurement and listing. This helps simplify documentation expectations for wholesalers, installers, and fleet buyers who prefer recognizable compliance marks for stocking and resale.

Built for Everyday Use

K1C Series 5202 combines clear performance figures, white 6500K output, and a cooling system built around dual copper heat pipes, a silent fan, and an aluminum structure. With an external intelligent driver, polarity protection, and controlled road coverage intent, it is positioned as a stable, practical LED headlight bulb option for vehicles using the 5202 fitment. Warranty coverage is 18 months, supporting regular use in daily driving and professional applications.
