Is this something to be concerned about (taken from the link)?
"Note: These bulbs are designed for interior use. They can be used in an exterior application but it is not road legal to do and, in addition, due to technical differences between LED and halogen technology, a vehicle warning light may be triggered depending on the configuration of your vehicle. This is more likely to happen if your car was manufactured after 2005. Should you choose to use the product in an exterior application, and a warning light is triggered, we are unfortunately unable to provide any guidance as to how to disable this."
