Modern Headlights

Calling SlantSixDan...
I figure eventually a LED headlight will pop up that looks like an OEM muscle car era headlight(no clear lens)

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.

work Better than said OEM bulb(better light pattern), wont have to splice a single wire(same plug) and no bucket mods either or empty your wallet to purchase a pair of them AND Get this......actually be DOT Legal.

Yup, several of those exist right now. See post № 11 of this thread.

with a few other LED bulbs in other areas such as taillights

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.
