Driving at night can be dangerous, especially if you don't have headlights that are working properly. Upgrade your car with a new headlight assembly and you'll be able to see the road in front of you much better when it's dark out. Not only will this make driving at night safer, but it will also help you avoid getting pulled over for having defective headlights.
