K1C Series 9012 LED Headlight Bulb for Cars and Trucks

Universal for Cars and Trucks

K1C Series 9012 is designed as a straightforward LED upgrade for vehicles that use the 9012 bulb type. The goal is broad compatibility and an installation experience that feels predictable for daily drivers, commercial vehicles, and workshop retrofits. Polarity protection is included to help prevent mis-connection on platforms where plug orientation can vary, reducing avoidable installation issues. For distributors and installers, this compatibility-focused approach helps support a wider vehicle list while keeping the product logic simple: a single 9012 model aimed at reliable fitment and stable performance.

Powerful Performance

The light engine uses four GC-7035 LED chips and targets a 360° beam angle specification to support consistent light distribution in headlamp optics. Electrical operation is rated at DC 9–36V, and input current is 5.0±0.5A at 13.2V, which aligns with common vehicle electrical systems. Output is presented in two states to reflect real usage over time rather than only a quick moment after power-on. Initial power output is 68.14W per bulb with an initial measured output of 5948 lumens per bulb. After 30 minutes, stable running values are listed at 61.68W per bulb and 5016 lumens per bulb. Color temperature is rated at 6500K with a ±500K tolerance, delivering a crisp white appearance that works well for roadway contrast and sign visibility.

Heat Dissipation System

Heat management is built around a combined system that uses dual copper heat pipes and active airflow. Copper heat pipes are used because they transfer heat efficiently away from the LED heat source, spreading it into the aluminum structure to reduce localized hot spots. A silent fan supports airflow through the heat sink area, helping maintain thermal performance during slow driving, idling, or warmer ambient conditions where passive cooling alone can struggle. This cooling approach supports steadier operating temperature and helps limit brightness drop during extended runtime, which is especially important for drivers who spend long hours on the road or for vehicles that operate overnight.

Integrated Die-Casting Structure

The mechanical design uses a robust aluminum body that contributes both durability and heat capacity. High-brightness LED chips are integrated into a structure that supports stable positioning during vibration and temperature cycling. The 9012 version includes an adjustable chuck, allowing installers to fine-tune the bulb’s indexing so the emitter position aligns properly within the headlamp system. This adjustment helps improve beam formation consistency across different reflector and projector housings, making it easier to achieve a clean light distribution without trial-and-error swapping.

External Intelligent Driver

An external intelligent driver is used to manage current delivery to the LEDs. Keeping the driver outside the main bulb body helps reduce heat exposure for sensitive electronics and supports more stable regulation during long runtimes. In practical use, the driver helps control the transition from initial output to stable output in a more predictable way, which matters for customers who compare real performance after the lamp has been running for a while. The external design also supports easier placement within tight headlamp cavities because the driver can be positioned where space allows, rather than being confined to the hottest region behind the LED module.

Precise Cutoff and Road Coverage

The beam control concept focuses on useful road coverage with an anti-dazzle intent. A more defined cutoff helps keep light directed onto the road surface instead of scattering upward, which supports safer night driving when traffic density increases. Controlled coverage also helps maintain clearer lane definition and roadside awareness, giving drivers a beam pattern that feels organized rather than overly dispersed. With proper installation and aiming, this approach supports visibility improvements while helping reduce glare for oncoming traffic.

Low Beam and High Beam Performance

Low beam performance emphasizes a clean boundary and balanced foreground illumination to support comfortable night driving. High beam performance emphasizes down-road reach while maintaining practical spread for roadside awareness. The intent is a usable combination: low beam that remains controlled and consistent, and high beam that provides stronger forward information when the road opens up. For workshops and fleet users, this balance helps deliver a lighting upgrade that is easy to validate visually and practical across mixed city and highway conditions.

Compliance

The product is marked for CE and RoHS compliance, supporting common documentation needs for distribution and resale. These marks can help simplify listing and procurement workflows in regions where compliance identification is frequently requested, making it easier for wholesalers and installers to move the product through standard channels with fewer barriers.

Built for Everyday Use

K1C Series 9012 combines clear performance figures, a 6500K white output target, and a cooling system that includes dual copper heat pipes, a silent fan, and an aluminum structure. The adjustable chuck supports fine alignment, and the external intelligent driver helps stabilize current delivery for consistent real-world output. With polarity protection, controlled road coverage intent, and CE and RoHS compliance, it is positioned as a practical LED headlight bulb choice for vehicles that use the 9012 fitment. Warranty coverage is 18 months to support regular use across daily driving and professional applications.
