How do you change dim headlights on a '93 Ford Explorer?

1. You may have a bad ground. 2. The battery may not be charging, due to a bad battery or alternator

The dim lights are probably caused by hazed,cloudy, or fogged out plastic lenses. I detail headlights at used car dealerships and I use a product called CrystaLenz. Their product works extremely well without removing the lens or using any special tools. You can get more info. at

How does that even answer the question?
