CAN Bus LED replacement bulbs can fit many vehicle applications such as trunk lights, under-hood lights, dome lights, map lights, and footwell lights. This 194 bulb replaces a variety of traditional bulbs including 194, 168, and T10. They feature 5 LEDs (5050 SMD) that are mounted radially to create a 360° viewing angle for improved light emission while reducing hot spots. Error-free LED bulbs are designed to communicate with your vehicle's CAN Bus computer system and prevent "bulb out" error messages. Short, tower-style design with a miniature wedge base for easy plug-and-play installation. The energy-efficient bulb operates at 12V DC and is designed to last 30,000 hours in your car, truck, SUV, or van—25 times longer than incandescent bulbs.
