Nighthawks
were the last worthy sealed beams on the market when they were made in America. Now they're very poorly made in China, with severely lousy output (dim, blotchy, useless) and very fragile glass that breaks if you stare hard at it.
If you want affordable and solidly decent, it's
these lamps with
these bulbs.
If you want the top-of-the-heap Koito halogens, or the (legitimate) projector BiXenons, ping me.
If you want LEDs, be careful; there's a(nother) mountain of fraudulent/unsafe junk on the market, including all "LED bulbs" that fit in halogen headlamps (see
here) and a whole lot of toys shaped like whole sealed beam headlamps. But there are some good-to-excellent ones on the market, too. the
Peterson 701C is pretty good, and so is the
Truck-Lite 27270C. By a big, big margin the king daddy of them all is the
JW Speaker 8700, which comes in black or chrome. All three of these are well made in America. There's a lot of lookalike copycat junk "recommended" when you look at these; ignore them. Super-shіtty junk from NAPA, too; avoid it.
Whatever headlamps you wind up using, the most important thing about them is
how they're aimed.
