On the new vehicles when one bulb goes out a light comes on the dash board, and actually two bulbs ahould be replaced, one on the right and one on the left, the reason is the new bulb will have a diferent resistance from the old bulb and that difference will triger all sort of mesages for the computer, that can and will shut engines down, or as this case lead the computer to shift out of drive into neutral, we experienced this with the new fire aparatus units when the firemen were replacing light bulbs burnt out, it took a time for them to understand that both sides had to be replaced.
Word of caution chinese light bulbs have different resistance even for brand new units and the problems will continue, American, German, Japanese light bulbs have the same resistance by wattage.
