Not gonna happen. It's all projectors and/or clear lenses. We're not going back to lens optics, and even if someone were to go after the collector-car market with a lens-optic LED headlamp, it still wouldn't look like a sealed beam, because the optical facets and prisms themselves would have to be very different (because the light source is very different). Also, such a headlamp would be much less efficient/much lower performing than a clear-lens headlamp.
Yup, several of those exist right now. See
post № 11 of this thread.
Careful-careful-careful. Most (almost all) of what's on the market is junk, including the lens-shaped LED panels.
Clean the front park/turn and rear brake/tail/turn lamp lenses in hot soapy water. If the reflectors are at all dull or peeling, stuff wads of masking tape in the bulb holes (or remove the sockets if they're the removable type), clean the reflectors with alcohol, then spray them with readily available "chrome" spray paint, which is practically ideal for the task.
Then put
these in the brake/tail lights and
these in the reversing (back-up) lights. Do not substitute, get these specific ones! You'll need
this turn signal flasher. There's not yet an acceptable (safe/effective) LED replacement for 1157NA for the front turn signals, but there will be before long. More details
here.
