Close, pretty sure it's from a '64 Pontiac Gran Prix. Here's a pic of a couple more. Usually when you find them, the chrome on the cast zinc bodies is pretty pitted. And the plastic lens is usually "crazed" as well. I've been looking for a few years now and then for repop lenses, but no luck so far. (I did find '63 and '65 lenses reproduced, on eBay, but the guy said he didn't have '64's) They're originally set up for an 1157 bulb. If you want headlight brightness, you gotta do something about that, but not too much or you'll melt the plastic lens.
