If you forget to periodically check your headlights, there's a fleet of black-and-white cruisers who will gladly do it for you.
Unfortunately they charge quite a bit, and that's if you don't have to show up in court with a picture of your car with both
lights on to prove that you fixed it. So go ahead and take a peak at the front of your car. If you're lazy you can wait until
you're behind a big trailer and check them from your driver's seat.
