I have a 2003 car and had a headlight that burned out. Getting the car inspected and they offered to replace it. Was like 3 dollars with a little bit of labor. Was chatting with the mechanic and he said that the newer cars have these proprietary Light bulbs that are ridiculously expensive like over 20x more expensive. Sounds like expensive consumer-hostile bullshit to me! Hope my car lasts for another 150k miles.
