K1C Series PSX24 LED Headlight Bulb for Cars and Trucks

Universal for Cars and Trucks

K1C Series PSX24 is designed for vehicles that use the PSX24 bulb type and is positioned as a practical headlight upgrade for both passenger cars and light-duty trucks. The goal is broad compatibility and a predictable installation experience for workshops, distributors, and fleet users who need a reliable solution across multiple vehicle platforms. Polarity protection helps reduce installation risk on vehicles where plug orientation can vary, supporting smoother retrofits and fewer avoidable connection issues. This makes PSX24 fitment easier to support at the wholesale level because the product logic stays clear and the installation outcome is more consistent.

Powerful Performance

The light engine uses four GC-7035 LED chips arranged to support stable optical positioning in headlamp systems that accept PSX24 bulbs. Electrical operation is specified at DC 9–36V, which aligns with common automotive electrical environments, and input current is listed as 5.0±0.5A at 13.2V to describe operating draw under a standard reference point. Beam angle is specified at 360°, supporting balanced light distribution when the bulb is installed in suitable reflector or projector optics. Performance is presented as both initial and stable values to reflect real use after the bulb has been running. Rated power is 70W per bulb, with an initial measured power of 68.14W and a stable running power of 61.68W at 30 minutes. Lumen output is also expressed in a real-use way, with a theoretical figure of 6000 lumens, an initial measured output of 5948 lumens per bulb, and a stable value of 5016 lumens per bulb at 30 minutes. Color temperature is rated at 6500K with a ±500K tolerance, delivering a crisp white beam appearance for roadway contrast and sign readability.

Heat Dissipation System

Thermal control is built around a combined cooling architecture that uses dual copper heat pipes plus active airflow. Copper heat pipes help transfer heat away from the LED heat source quickly and spread it into the aluminum structure, reducing localized hot spots that can accelerate lumen drop over time. A silent fan supports airflow through the heat sink area, which is especially helpful during slow driving, idling, or warm ambient conditions where passive cooling is less effective. This cooling design supports stable operation during extended night driving, helping the bulb reach a steady operating point and maintain more consistent output throughout a driving session rather than only showing a strong peak at startup.

Integrated Die-Casting Structure

The bulb assembly is built around a robust aluminum structure that provides both durability and thermal mass. High-brightness LED chips are integrated into a compact mechanical layout designed to stay stable under vibration and temperature cycling that are common in automotive environments. The PSX24 version is specified with a non-adjustable chuck, keeping installation orientation fixed for the intended fitment geometry and reducing setup variability during installation. A fixed indexing approach can be beneficial for repeatability at the workshop level, because the installation outcome depends less on manual adjustment and more on correct fitment and proper headlamp aiming.

External Intelligent Driver

An external intelligent driver is used to regulate current delivery to the LED chips. Locating the driver outside the main bulb body helps reduce heat exposure for sensitive electronics and supports steadier regulation during long runtimes. In practical use, stable current control helps the transition from initial output to stable output remain predictable, which matters to users who evaluate real brightness after the lamp has been running for a period of time. The external driver layout also provides flexibility for placement inside tight engine-bay and headlamp cavities, because the driver can be positioned where space allows rather than being confined to the hottest area directly behind the LED module.

Precise Cutoff and Road Coverage

The beam concept emphasizes controlled road coverage with an anti-dazzle intent. A cleaner cutoff helps keep light focused on the road surface and reduces stray upward spill that can contribute to glare when there is oncoming traffic. Controlled distribution also supports clearer lane-edge visibility and more organized illumination, which many drivers prefer over a scattered beam that looks bright up close but fails to provide useful down-road information. With correct installation and proper aiming, the result is a beam pattern that supports both visibility and driving comfort in mixed traffic conditions.

Low Beam and High Beam Performance

Low beam performance is intended to deliver a defined boundary and balanced foreground illumination for comfortable night driving. High beam performance is intended to provide stronger down-road reach while maintaining practical spread for roadside awareness. This balance is important for real driving, where low beam must remain controlled in traffic and high beam must offer meaningful reach on darker roads. When installed in suitable headlamp optics and aimed properly, these patterns help drivers gain usable visibility rather than only a bright hotspot near the vehicle.

Compliance

The product is marked for CE and RoHS compliance, supporting common distribution requirements and documentation expectations in many markets. These marks help streamline procurement and listing workflows for wholesalers and resellers who need recognizable compliance identification when stocking and selling LED headlight upgrades.

Built for Everyday Use

K1C Series PSX24 combines clear performance figures, a 6500K white output target, and a cooling system built around dual copper heat pipes, a silent fan, and an aluminum structure. The external intelligent driver supports stable current delivery and helps maintain predictable output over time, while polarity protection reduces installation risk across varied vehicle platforms. With controlled road coverage intent and CE and RoHS compliance, this PSX24 LED headlight bulb is positioned as a practical option for daily driving, workshop retrofits, and wholesale distribution. Warranty coverage is 18 months, supporting regular use in both personal and professional vehicle applications.
