Can,t see a rim that holds the gl*** in so they must be depressed beam lights. Push the gl*** in against a few springs and twist it to remove. If the joints are full of sand and **** it will be real tight. Wash the joints out first with WD40 or water. Nash and Pontiac had them.
If there are any numbers or letters on the lense you can look them up. I don't remember the website. If you search headlight lense id on the net the site comes up easily. They look like Nash or large Mopar to me. 35 or 36
