Once upon a time there were "American" sealed beam headlamps (visit a museum) and "European" seperate bulb and reflector headlamps. Modern cars all benefit from halogen bulb technology but retro-fitting euro lamps in place of older sealed beams is a popular modification...and one you can sell to your wife as being for safety reasons!
Reto-fitting wipers has been discussed in previous posts. Try a search under "headlights".
