As the thread title says, here is a comparison of 25-year-old sealed halogen headlights and new Cibie housings with Philips X-Treme Vision H4 bulbs. Old headlight is shown on the left, new headlight is shown on the right.
New headlight covered, only old bulb visible:

Note that in the photo of the old headlight, the light stretches in a flat fuzzy beam across 3 panels of the garage door. In the photo of the new headlight, the light has a sharp top cutoff (reduces glare for other drivers) and stretches in a complex shaped beam with strong right-hand lighting (improves visibility off the side of the road) and is distributed across the entire 8-panel garage door and then some.
Visibility is clearly going to be a lot better with these new lights! With the old lights, I struggled because I had to point them down a bit to avoid getting angry flashes from oncoming drivers who were experiencing glare. I also could not see anything to the side of the car at all. It used to feel like driving in a very close tunnel, and I suspect that will no longer be the case! I will be able to aim the new lights better without pissing anyone off, and I'll be able to see parts of the road that are not directly in front of my car.
I am actually not a fan of how bright the new lights are, as I prefer my headlights a bit dimmer to keep from blowing out my night vision. Super high contrast settings fuzz my reaction times and give me a headache. I think when these bulbs die I will scale it back down by one notch to the Vision Plus bulbs.

When I show up at a car show and my car is covered in mud, it's probably because I drove 2000 miles to get there
