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 www.crystalenz.com

How does that even answer the question?
