Use the names to search eBay and then look for the product. I did not link to the listings since they can change and then the links are useless. This way you can search the seller.

Both listings indicate they are glass.

FWIW ... one are the housings only. The other is housing plus LED's. A reply from the latter indicated that these are DOT approved.

I currently have the former on my Christmas list and if I get them can tell you more in January
