I got interior bulb set on e-bay. $20. Can't remember name of manufacture but it was the only kit in white for 2010+ taurus. It also came with licence plate bulbs. Puddle lights are incredibly expensive for what they are. I can't see myself paying that much. Thanks to ford for using the same poor design for at least 15 years that I know of. Puddle lights are non servicable sealed units. I come up with a way to retrofit my own. Waiting for 31mm bulbs to arrive. Will post my retrofit project if it works. That's all I can help you with but it's a start.
