For those of you who have fog lights installed, is it possible to change the bulbs in your LED fog lights? If possible, I would like to change my white LED fog light bulbs with amber LED bulbs. The owners manual is vague on the topic of LED bulbs (both head and fog light). In fact it implies that the bulbs are sealed and that the head or fog light unit would have to be taken to a dealer to get replaced/fixed if a bulb were to burn out. Is this true?
