change to brighter head lights

An often overlooked aspect of headlight intensity is the condition of the mirrored reflector inside the lamp itself. Degradation (oxidation) can occur on glass sealed beams (quad or double style) as well as modern modular lamps with replaceable bulbs. If you see moisture condensing inside the lens or a chip/crack in the surface of the lens, chances are you have this condition. At night, turn on the headlamps and look to see how much light is leaking out the REAR of the headlight assembly. Compare that with a new assembly. That's all light that isn't being projected onto the roadway as it should. If your headlights are over 10 years old, chances are there is some degradation of the reflector as well as the lens. If it's bad enough, replacement is about the only way to restore beam intensity and focus.
