Universal for Cars and Trucks K1C Series H4 and H13 LED Headlight Bulbs

K1C Series H4 and H13 LED headlight bulbs are built for wide vehicle coverage in everyday cars and light duty trucks, with an installation focused design that helps keep beam positioning consistent across different headlamp housings. The platform uses an adjustable chuck to support proper alignment during fitment, which is especially useful for workshops and distributors serving multiple vehicle models. With a 9 to 36V DC operating range, the bulbs are intended to work across common electrical systems while maintaining stable output characteristics during real runtime conditions.

Technical Data

For H4 and H13 applications, each bulb is rated at 70W and uses a 360° light emitting layout. Color temperature is specified at 6500K ± 500K, targeting a clean white output that suits modern headlamp optics. Performance data is provided for both high and low beam operation. Actual power output is listed at 66.25W per bulb on high beam and 65.79W per bulb on low beam. After 30 minutes, stable power output is listed at 54.88W per bulb on high beam and 50.54W per bulb on low beam, which helps set expectations for sustained use. Theoretical light output is specified at 6000LM per bulb, with actual lumens listed at 5380LM per bulb on high beam and 3828LM per bulb on low beam. Stable lumens after 30 minutes are listed at 4438LM per bulb on high beam and 2934LM per bulb on low beam. Electrical draw is specified as 5.0 ± 0.5A at 13.2V, supporting practical planning for vehicle electrical load.

Heat Dissipation System

Thermal control is central to keeping LED headlight performance consistent, especially when the bulbs run continuously at night driving temperatures. This design uses a heat transfer pathway built around Double Copper Pipes to move heat away from the LED emitting area and into the main body where it can be dispersed. The airflow component is handled by a Silent Fan, which is intended to maintain cooling performance while keeping operating noise low for everyday use. Together, these elements form a heat dissipation system that targets stability over time rather than short peak output, helping the bulbs maintain their operating state through longer drive cycles and higher under hood temperatures.

Because headlamp housings can vary widely in available space and airflow, a compact cooling layout matters. The combination of copper heat transfer and active airflow is used to support stable output after warm up, matching the listed stabilized power and lumen values at 30 minutes. This approach is useful for installers who want predictable results across different vehicles and for wholesale customers who need a consistent specification story when supporting multiple markets.

Product Structure

The platform highlights a structural layout designed for durability and repeatability. The body uses an integrated diecasting structre to provide a rigid base and consistent geometry for assembly, which helps keep critical parts seated properly during vibration and long term use. At the light source, high-brightness LED chip placement is kept aligned to support controlled optical positioning, which is essential for beam shape in reflector and projector style housings. The driver is arranged as an External Intelligent Driver, separating key electronics in a way that supports stable operation under varying voltage conditions within the specified range.

In addition to the core structure, the cooling components are integrated into the overall layout rather than treated as add ons. The Silent Fan is built into the rear portion of the assembly to provide continuous airflow over the heat dispersing area, while the Double Copper Pipes connect the heat generating zone to the thermal mass of the body. This structural approach aims to keep the bulb compact enough for common headlamp installations while still supporting sustained runtime expectations. For professional installers, the adjustable chuck adds a practical layer of alignment control so the bulb can be oriented correctly in the socket, which helps maintain a consistent beam pattern after installation.

Precise Cutoff Road Coverage

Beam control is presented as a key benefit, with an emphasis on precise cutoff road coverage rather than uncontrolled glare. The intent is to support clear forward visibility while reducing stray light that can distract oncoming traffic. The beam concept is described with an anti-dazzle design that focuses light where it is needed on the road. For drivers, this means more usable illumination on lanes and shoulder areas without excessive upward scatter. The coverage message also emphasizes zero blind spots, and includes the phrasing zero bind spots, pointing to the same idea of minimizing dark gaps within the illuminated area so the road surface remains readable and consistent.

This kind of beam discipline is particularly important for H4 and H13 dual beam formats, where the headlamp must transition between high and low beam use cases. With the listed output figures for both modes, the design targets practical illumination for each beam setting while keeping the boundary controlled. For distributors and installers, the focus on cutoff and coverage supports a clearer positioning story when customers care about visibility and comfort, not only raw brightness.

Certification

Compliance support includes CE and RoHS certification, which helps streamline documentation for wholesale purchasing and cross border distribution. These certifications are often part of supplier qualification and product approval workflows, especially when customers need to align with regional compliance expectations. The warranty is specified at 18 months, providing a defined coverage period that can be used in channel policy planning and after sales support discussions.
