CAN Bus LED replacement bulbs can fit many vehicle applications, such as map lights, dome lights, trunk lights, and footwell lights. This 4410 LED festoon bulb replaces a variety of traditional bulbs including 4410, 578, and 12864. The 44mm bulb features 8 LEDs (5050 SMD) on a rectangular PC board (printed circuit board). The LEDs are mounted on one side of the board for direct illumination without wasted light. The error-free LED bulb is designed to communicate with your vehicle's CAN Bus computer system and prevent 'bulb out' error messages. A festoon base allows for simple plug-and-play installation. The energy-efficient bulb operates within a 10-14.8 VDC range and lasts 25 times longer in your car, truck, or SUV than incandescent bulbs. Available in warm white, natural white, or cool white.
