I would say those are 1950 Pontiac taillights.

If not, they are close and you can just convert to the Pontiacs, as they are readily available.

Like these:

Here are the buckets, looks like what you have:

I have a set and can measure the dimensions if you need them, (the links above have some dimensional specs), I will just have to filch them out of my parts bin.

Edit: Looked at the pics again and they are not the 50 Pontiac, they have a higher dome. The Pontiac lights are cooler in my opinion, but very similiar with the dark red round domed lens. Again, you may just want to convert to the Pontiacs and get the same look, but be able to find replacement parts.
