Last year, one of the headlights on my 2011 Outback burned out, and since I was due for an oil change w/in a few days, I told the dealership’s service advisor to replace the headlight bulb. To my surprise, it turned-out to be free because I had only a little more than 99k miles on the odometer at that point, and I was informed that Subaru had extended the warranty on headlight bulbs to 100k miles.
If the OP has less than 100k miles on the odometer, I would suggest that he check with the dealership to determine if his 2014 Outback had its headlight warranty extended to 100k miles.
