7KG26 Series 26W 3020SMD LED Bulb
The 7KG26 series represents a new generation of high-output LED bulbs built for durability and consistent illumination in modern automotive lighting. Designed with a high-density 3020 SMD array, each bulb contains 26 advanced LEDs optimized for both brightness and efficiency. Whether used for signal, brake, or reverse lights, this series delivers a clear, focused beam that enhances road visibility and safety while maintaining a compact structure that fits seamlessly in standard lamp housings.

High-Efficiency 3020 SMD LED Array
Each 7KG26 bulb features 26 pieces of 3020 SMD chips, precisely arranged for maximum light output and uniform coverage. These high-intensity diodes offer a significant performance advantage over older-generation chips by providing greater brightness with lower heat generation. The optimized chip spacing ensures even light distribution, preventing hot spots and shadowing in the lamp reflector. The result is a crisp, vibrant beam suitable for all types of rear lighting applications, including brake, turn, and reverse functions.

CK Socket Option for Dedicated Wiring Systems
For vehicles that use CK wiring on their signal positions, the 7KG26 Series offers a dedicated CK socket version. The plug geometry matches the original connector to help maintain a secure fit and stable electrical contact under vibration. This dedicated option simplifies installation on CK-type vehicles and reduces the risk of poor contact or flickering that can occur when using a universal plug.

Six-Sided LED Layout for Uniform Emitting
The light-emitting structure of the 7KG26 bulb is arranged on six sides around the core. This layout surrounds the reflector with light, helping to recreate a full 360-degree style output similar to traditional filament bulbs. The evenly distributed chips reduce dark spots and help the lamp housing project a smooth, continuous signal that is easy to see from the rear and side of the vehicle.

Ventilated Housing for Better Air Convection
The outer shell adopts a hole-based design that opens channels through the body of the bulb. These openings increase air convection around the light source when the vehicle is moving and allow hot air to escape more easily in confined lamp housings. By helping hot air move away from the LED core and electronics, this structure supports more stable operating temperature during long use.

Original-Style Plug for Reliable Connection
The plug end of the 7KG26 Series is shaped to follow the outline of the factory bulb base. This original-style plug design helps the bulb lock into the socket firmly and keeps contact pins aligned with the OE terminals. A firm mechanical connection is important for resisting vibration, ensuring consistent current delivery and reducing intermittent faults in turn, brake or tail light applications.

Double-Sided Aluminum Substrate Driver
Inside the bulb, the driver and components are mounted on a double-sided aluminum substrate. Aluminum provides rapid thermal conductivity so heat from the driver and LEDs is transferred away quickly compared with fiberglass boards. The design helps lower the operating temperature of critical components and supports a lower defective rate over time. Front and back views of the substrate show an organized layout with zener diode, inductance and imported IC components working together for stable current control.

Optimized Driver Compared with Conventional Bulbs
When compared with typical LED bulbs that use multi-layer fiberglass substrates and bulkier components, the 7KG26 driver layout is more compact and thermally efficient. The streamlined design helps reduce unnecessary bulk while improving heat flow paths from the electronics to the surrounding aluminum body. This contrast highlights the focus on reliability and long-term stability rather than simply packing more components into the housing.

Measured Output and Color Performance
Laboratory testing for the 7KG26 Series records strong luminous flux figures, with white light measured at approximately 1704.8 lm and power around 22.4 W under 12 V conditions. Yellow and red versions also deliver vivid output, creating clear turn and brake signals that stand out in traffic. The photometric report shows a well-formed spectrum and stable electrical parameters, giving installers clear reference data for real-world performance.

Aviation-Grade Aluminum Lamp Body
The core body of the 7KG26 bulb is machined from aviation-grade aluminum. This metal construction gives the lamp a solid feel and provides a direct thermal path from the LEDs and driver into the surrounding air. The aluminum body also resists corrosion inside lamp housings that face moisture and temperature changes. Combined with the ventilated structure, this material choice improves both durability and light stability.

Projector Lens Tip for Focused, Low-Glare Output
At the front end of the bulb, a reducing projector lens shapes the light from the top LEDs. This lens design concentrates part of the beam forward to enhance visibility while helping to avoid harsh glare. The light is guided into the lamp’s reflector and onto the road or signal surface in a controlled manner. This approach combines the strong output of the 3020 chips with a smoother visual appearance for oncoming drivers and surrounding traffic.

Overall, the 7KG26 Series combines a six-sided LED layout, robust aluminum construction, advanced driver design and tailored socket options to offer a bright, stable and durable upgrade for modern automotive signal and tail light positions.
