There's a mountain of unsafe garbage in the automotive lighting aftermarket, but there are also some very good products. "LED bulbs" for halogen headlamps are a total nonstarter, but the situation is pretty rosy for cars with sealed beams…like all A-bodies.
By a big, big margin the king daddy of them all is the
JW Speaker 8700 Evolution-2 in black or chrome. They are also available
with a heated lens.
The
Peterson 701C (in Peterson or Sylvania Zevo packaging -- same lamp) is pretty good. The
Truck-Lite unit is pretty good, also available
with heated lens.
And down from there is a whole lot of knockoff/fraudulent/counterfeit junk; don't buy.
(All these recommendable LED sealed beams I've linked are made in America!)
Get heated lenses if you do a lot of wintertime driving with heavy snow and slush; without a lens heater the LED headlamp lenses run cold so snow and ice can build up on them instead of melting off like they do from a warm halogen lamp.
Very important to make sure the lamps (new or old, LED or not) are
properly aimed.
