Oh yeah, I forgot to mention
Oh yeah, I forgot to mention the constant need to keep extra headlamp bulbs in the glove box of our 2013 Crosstrek and our 2005 Legacy GT wagon, not just one bulb, but two. We have had double bulb failures, once in the middle of nowhere, at dusk, on a very long road trip. We learned of the failure when we turned on the lights in approaching darkness, forced to drive the last hundred miles on fog lamps and brights only.
One also needs to keep a headlamp with good batteries in the car to change the bulbs in darkness, and the appropriate tool to remove the intake shroud, and a clean rubber glove to handle the new bulbs. That's a bit much to expect from the average car owner.
