This 6451 LED festoon bulb communicates with your vehicle's CAN Bus computer system and prevents "bulb out" error messages. It replaces a variety of traditional bulbs including 6451 and 4210 bulbs. The error-free bulb has a plastic-encased printed circuit board with an integral heat sink. LEDs are mounted to one side of the board for direct illumination with no wasted light. The 42-mm LED bulb has a festoon base for easy plug-and-play installation. This LED car bulb operates within a 9-16 VDC range and lasts 25 times longer on your car, truck, SUV, or van than incandescent bulbs. Use the cool white bulb for numerous vehicle applications, such as map lights, vanity lights, trunk lights, and footwell lights. Not sold in pairs. Price per bulb.

RV Frig Replacement Bulb

This is the perfect replacement for the bulb in my RV Frig. It's brighter, uses less electricity and doesn't get as hot as the original.
