Product Specifications

41mm Festoon Bulb with White LED Output

The CN360 K6 Series 41mm CANbus LED festoon bulb provides white illumination for matching reading lights, license plate lights, trunk lights, and vanity mirror lights. Its 41 mm length identifies the required festoon format. The bulb connects through metal contacts at both ends, with the lighting board and rear cooling structure positioned between them.

The listed luminous flux is 210 lm, with a rated power of 2 W and a 180° beam angle. These specifications describe the bulb's output and light distribution for suitable lamp assemblies. The vehicle's reflector, lens, and mounting position also influence how the light reaches the cabin, storage compartment, or license plate.

Six 3020 SMD LEDs on the Front Face

The lighting board carries six 3020 SMD LEDs arranged across its front surface. This compact array places the light sources together on one emitting face, allowing the bulb to direct white light toward the lamp lens or intended area. The arrangement fits within the 41 mm festoon assembly.

Correct orientation helps the lamp make use of the available light. In an interior reading or vanity mirror assembly, the LED face should point toward the cover that distributes light into the cabin. For trunk and license plate lamps, align it with the original housing's intended light path.

Finned Heat Sink Behind the LED Board

A rear heat sink with fins supports heat dissipation from the LED assembly. Its finned shape provides surface area within the compact bulb body, combining the lighting and cooling components in one unit. The heat sink forms part of the bulb's full profile and should be included in any clearance check.

Measure the original bulb and inspect the space inside the housing before replacement. The 41 mm length must match the holder, while the area behind the lighting board must accommodate the cooling structure. The original lamp cover should close normally once the bulb is seated between the contacts.

Built-In Current Regulation and CANbus Design

The K6 incorporates a constant current IC to help regulate the electrical supply to its LEDs. This 41 mm version has a specified input current of 150 ± 10 mA and operates within DC 9–16V. The driver components are integrated into the festoon assembly alongside the lighting board.

A CANbus-oriented design supports use with compatible vehicle lamp monitoring circuits. Monitoring behavior and lighting controls vary between vehicles, so the intended circuit should be checked after fitting. Confirm that the lamp operates normally and that the vehicle shows no unexpected bulb warning for that position.

Non-Polar Connection for Matching Applications

The non-polar connection allows the bulb to operate without assigning a specific positive and negative end. This helps simplify the electrical connection in a compatible holder. The LED face still needs to point toward the illuminated area, and both metal end contacts should sit securely without forcing the bulb into place.

Choose the 41 mm K6 for a lamp requiring this length, a compatible voltage range, and sufficient housing space. Listed uses include reading, license plate, trunk, and vanity mirror lighting. Matching the original bulb size, electrical requirements, and optical orientation helps ensure that the selected bulb suits its intended position and delivers white light where it is needed.
