Product Specifications

K1C Series P13 LED Headlight Bulb for Cars and Trucks

Universal for Cars and Trucks

K1C Series P13 is built as a universal-style LED headlight upgrade for vehicles that use the P13 fitment. The product positioning focuses on broad compatibility for everyday driving and workshop installs, including cases where headlamp cavities vary by vehicle platform and model year. Polarity protection is included to reduce installation risk when connector orientation differs, helping installers avoid unnecessary troubleshooting and making the retrofit process more predictable. This compatibility-first approach supports distributors and wholesalers who need one reliable option that can serve multiple customer applications without complicated selection logic.

Powerful Performance

The light engine uses four GC-7035 LED chips and targets a 360° beam angle specification to support consistent light distribution in suitable headlamp optics. Electrical operation is rated at DC 9–36V, and input current is listed as 5.0±0.5A at 13.2V to describe operating draw under a common reference point. Performance is presented in two states to reflect real behavior over time. Initial output is specified at 68.14W per bulb and 5948 lumens per bulb, while stable values measured at 30 minutes are 61.68W per bulb and 5016 lumens per bulb. The color temperature is rated at 6500K with a ±500K tolerance, delivering a crisp white beam appearance that supports roadway contrast and sign recognition during night driving.

Heat Dissipation System

Thermal management is designed around a combined cooling system that uses dual copper heat pipes plus active airflow. Copper heat pipes help transfer heat away from the LED heat source efficiently and spread it into the aluminum structure, reducing localized hot spots that can cause faster output drop. A silent fan supports airflow through the heat sink area, which is helpful during slow driving, idling, or warm ambient temperatures when passive cooling is less effective. This architecture helps the bulb reach a steady operating point and maintain more consistent brightness during extended runtime, which matters for real-world night driving rather than short-duration demonstrations.

Integrated Die-Casting Structure

The bulb assembly is built around a robust aluminum structure that supports both durability and heat capacity. High-brightness LED chips are integrated into a compact form factor designed to remain stable under vibration and temperature cycling. This P13 version is specified with a non-adjustable chuck, which keeps the installation orientation fixed to match the intended fitment geometry and helps reduce setup variability during installation. The overall structure integrates the mechanical frame, the thermal pathway, and the airflow zone so the lamp can operate reliably during long nighttime runs.

External Intelligent Driver

An external intelligent driver is used to regulate current delivery to the LED chips. Keeping the driver outside the main bulb body helps reduce heat exposure for sensitive electronics and can support steadier regulation during long operation. In practical use, regulated current delivery helps make the transition from initial output to stable output more predictable, which is important for customers who evaluate lighting after the bulb has been running for a while. The external layout also offers more flexibility when routing components inside headlamp cavities, because the driver can be placed where space allows instead of being confined to the hottest zone behind the emitter.

Precise Cutoff and Road Coverage

The beam concept emphasizes a precise cutoff and 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 coverage also helps drivers read lane edges and roadside conditions more clearly, delivering a beam pattern that feels organized rather than overly dispersed. With correct installation and proper aiming, this approach supports visibility improvements while maintaining better comfort for surrounding traffic.

Low Beam and High Beam Performance

Low beam performance focuses on a defined boundary and balanced foreground illumination for comfortable night driving in traffic. High beam performance focuses on stronger down-road reach while still maintaining practical spread for roadside awareness. Together, these patterns support mixed driving conditions, such as city routes where beam control matters and open roads where forward reach becomes the priority. For workshops, fleets, and end users, the goal is a lighting upgrade that is easy to validate visually through a controlled beam shape and practical on-road coverage.

Compliance

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

Built for Everyday Use

K1C Series P13 combines clear performance figures, a 6500K white output target, and a cooling architecture that includes dual copper heat pipes, a silent fan, and an aluminum structure. The external intelligent driver supports stable current delivery, and polarity protection helps reduce installation risk across varied vehicle platforms. With controlled road coverage intent and CE and RoHS compliance, it is positioned as a practical LED headlight bulb choice for vehicles using the P13 fitment. Warranty coverage is 18 months, supporting regular use across daily driving and professional applications.
