The original-type headlamps are sealed beams. No matter what brand or when made, plain or halogen or "performance halogen", these are primitive and barely marginally adequate. They produce a dim, narrow smudge of poorly-focused, brownish light, very little light on the road surface, no side spill, and a great deal of upward stray light that causes backdazzle in bad weather. You can do much better than these, but you have to be picky and shop carefully because much of what's on the market is unsafe/fraudulent junk (though of course all of it is advertised as an "upgrade").
The most important thing to keep in mind is that whether or not you like your headlights is not the same question as whether or not your headlamps are safe and effective. The difficulty is, what we feel like we're seeing isn't what we're actually seeing. The human visual system is a lousy judge of how well it's doing. "I know what I can see!" seems reasonable, but it doesn't square up with reality because we humans are just not well equipped to accurately evaluate how well or poorly we can see (or how well a headlamp works). Our subjective impressions tend to be very far out of line with objective, real measurements of how well we can (or can't) see. It's not because we're lying to ourselves or fooling ourselves or anything like that, it's because our visual systems just don't work the way it feels like they work.
Which means most internet "reviews" of a headlamp are useless at best.
There are good options worth buying in all four of the sealed beam sizes; large and small/round and rectangular, but in some sizes there are more options than in others, and the price range for lights worth having varies by lamp size/shape. In general you won't get what you don't pay for, but in some cases there are nice bargains to be found on lamps worth switching on at night.
