Like the OP, I too am getting old and require more light for night driving.
Here is my experience with brightening up headlights. I hesitate on switching to LED bulbs because some vehicles have trouble with LED headlights.
If your headlight lens is not clear as glass any longer, if having trouble seeing the detail inside, then you really want to polish the lens. It's not hard to do, especially using a polisher/buffer tool of some kind.
This is another vehicle I own, but the problem is the same.
You want to turn this.....

into this.....

using this.....

In the given example, I removed the housing and polished it while holding it in my hand, using the buffer in the position shown resting on the floor. It is best to remove the housing and polish it off the vehicle for best results and to avoid damage to surrounding paintwork.
The process is not a cover-up or band-aid solution. It makes the lens like see-thru glass again by removing oxidized material using a very fine abrasive compound. The example pictured also has some stone chip damage. Anything you can feel with your fingernail will remain. Buying a new lens is the only way to make them go away.
Next is the selection of your headlight bulb itself. Brighter halogens are sold at places like Walmart and they do make a difference. Here is one example for a 2007 E350 Super Duty, bulb 9007. The trade-off is that the brighter bulbs don't last quite as long as the standard ones.
