The extra bulbs within the tail lights are emergency bulbs. When a tail/brake light goes out the extra bulbs are used as reserve and alert you in the dash display. When you change the bulb the reserve automatically distinguishes itself, until the next time anyway. It's discussed in the owners manual.
