As @
Chombi1 says, a lot of the lights available in the 70's were not that great (such as that Wonder headlight) and had some odd details.
Here's the page from a 1980 Bike Warehouse catalog showing the Wonder headlight, the Belt Beacon, and the familiar white/red light that straps to an arm or leg...
Personally, when I think of vintage lights that look good, I'm thinking more of the aluminum or chromed lights that were used on touring or randonneuring bikes... which makes sense, as they are the ones that get ridden at night.
I've still got my old Jos block dynamo, which is a nice, small light. Not at all bright by modern standards, though.
Peter Weigle's flickr pages show some of the neat old vintage lights....

The only modern light(s) that I'm familiar with are the Schmidt Edelux lights that are built from aluminum. They are dynamo lights, which isn't a surprise, and use a LED and excellent optics.

B&M has a dynamo light with a vintage look too. No idea how it compares to the Edelux.

I have vague memories of a battery powered light with similar aesthetics, but don't recall any details.
Personally, I'm tinkering with retro-fitting LEDs into my old Jos dynamo light, and hope that it can be a guide for others to upgrade some of their vintage lights with better performance. It would be nice to see some of the really cool old lights be used again instead of just gathering dust on a shelf.
