There are suppliers in the country but pretty much all aftermarket headlights are going to be made outside the country. That's why they're usually so cheap cost-wise compared to factory OEM headlights; aftermarket quality is usually so so and more than not they have leak issues due to cheaper quality sealant and a poor seal around the lens. I bought an aftermarket pair for my Monte Carlo which, sure enough, was made in China. I didn't have issues with them, since I took them apart to work on them and re-sealed them myself, but I could tell out of the box the seal was not great. That and the bulb connectors were crap. After a few months I went back to a brand new factory OEM pair.
