@slantsixdan any opinion on these LED lights?

Complete garbage. Those aren't LED headlamps; they're H4 halogen headlamps with bogus "LED bulbs". Useless, dangerous, illegal trinkets. Do not buy.

It is (still) a pointless waste of time climbing the tall mountain of fetid junk on the vehicle lighting market, picking up random bits off it and going "What about these? What about these? What about these? Ooh, hey, I saw these on YouTube, what about these?".

There are several good, legitimate LED headlamps to fit A-bodies. Most of them are made in the USA. These are the best ones. These and these and these are good, too. This one is passable. There are useless Chinese knockoffs of all of these, too.
