White Illumination for 39mm Festoon Lamp Holders

The CN360 K6 Series 39mm CANbus LED festoon bulb is designed for compatible reading, license plate, trunk, and vanity mirror lights. Its 39 mm length matches lamp holders requiring this festoon size. A flat LED board sits between the two metal end contacts, placing the light-emitting surface toward the lamp lens or the area being illuminated.

The bulb is rated at 2 W and has a listed luminous flux of 210 lm. White light and a 180° beam angle provide a defined lighting specification for suitable interior and license plate applications. The surrounding lamp housing, reflector, and cover work with the bulb to determine the final distribution of light.

Six 3020 SMD Light Sources

The K6 lighting board carries six 3020 SMD LEDs. Their arrangement creates a compact emitting area across the front surface of the bulb. Grouping the LEDs on this face makes the orientation of the board an important part of achieving useful illumination inside the intended lamp assembly.

For reading and vanity mirror lights, face the LEDs toward the lens that spreads light into the cabin. For a trunk lamp, direct the emitting face toward the storage area. License plate installations should likewise position the LED face to work with the original housing and illuminate the plate through its intended light path.

Integrated Finned Cooling Structure

The rear of the assembly features a finned heat sink that supports heat dissipation from the lighting board. Its shape provides cooling surface within the festoon body, keeping the light sources and thermal structure together in a compact unit. The fins form part of the complete bulb profile.

Check the space behind the original lamp before fitting the replacement. A 39 mm holder establishes the required contact spacing, but the housing must also accommodate the LED board and rear heat sink. The bulb should sit securely with enough room for the lamp cover to return to its normal position.

Constant Current Control and CANbus Design

A built-in constant current IC helps regulate the supply to the LEDs during operation. The specified input current for this 39 mm version is 150 ± 10 mA, and its operating range is DC 9–16V. The driver is integrated into the bulb assembly together with the lighting components.

The CANbus-oriented design supports use in compatible vehicle lighting systems that monitor bulb operation. The behavior of these systems varies with the vehicle and lamp circuit. After fitting, check illumination through the normal controls and confirm that the vehicle does not display an unexpected bulb warning for the selected position.

Non-Polar Connection and Application Matching

The bulb's non-polar design allows either end contact to receive the positive supply in a compatible holder. Electrical polarity therefore does not determine which end must face a particular direction. The LED board should still be aimed toward the lens or illuminated surface, and both contacts should remain securely seated.

Select this bulb for applications requiring a 39 mm festoon format, with a matching voltage range and sufficient housing clearance. Its listed uses cover reading lights, license plate lights, trunk lights, and vanity mirror lights. Confirming the original bulb size and lamp arrangement helps match the K6 to the intended function and make effective use of its white LED output.
