I've put Euroheadlights on my two cars (both '93's), but they're expensive (and even harder to get nowadays). The reason I did that is that I've used e-codes (they're the substitutes for sealed beams) since the early 1970's in every one of my cars that could take a sealed beam (which was until I owned post-'84 240s), and I can't put up with anything less, especially with my (now) old man's eyes.

Don't settle for just putting more wattage in your car's lousy proprietary headlights -- the problem is not the wattage, but the optics that are not focusing the light usefully.

I've lately decided that if I ever buy another 240, I wouldn't want cost of still another set of Euroheadlights, so I'd fabricate some mount that let me place an e-code (especially a 7 inch round, which I found, over the years, had excellent performance and wouldn't necessitate installing a pair of e-codes such as 5-1/4 rounds in the same crowded space). I don't see why it couldn't be done. You only have to be a little artistic with the "surround" -- maybe some sculpted wood. And you need the right size headlight mount, adjustable, to install in place of the awful proprietary headlamps.

Certain big-rig Volvo trucks used (as a cost reduction option) 7 inch round sealed beams with their surround that fitted the space of the headlights (which were identical to the 240's headlights). But their fiberglass surround was very expensive.
