From what I've seen of the photos, they all look like glass. The search I did above yielded results for "1995 Dodge Ram 1500 headlamp assembly". I would not consider buying these jsut yet until you get the chance to speak with a representative of that company.
A lot of companies are doing their best to get away from the hassle of speaking to customers and providing a stictly web-based communication, which means if you get tehw rong part, the onyl way you can deal with them is via email. YOU need someone that YOU can speak with immediately if YOU have an issue concerning YOUR car.
Call up a local Dodge dealer and get the part numbers of the headlamp assemblies. Take those part numbers and search the net by typing in "headlamp assembly [part number] mopar". I don't know; your OEM may be plastic (which is probably why you are searching for glass) but that part number will help you locate and identify the plastic part for comparison to other glass parts.
There is an eBay link included witht he search I did for you.
Best of luck to you!
