The two on the left are just aftermarket accessory dash lamps. You are missing the sockets, but can still slide over a array of small lamps. They were made by a company called Perko
I have had a nice complete one of those dash lamps on the left since I was in my teens and still havent found a good use for it. The one on the the right is a big truck bed marker light. We used to see them all the time at swap meets. Tim
The jeweled ones were also commonly used in the day on Model A's and Harley Davidsons. Usually some on eBay and can sell for a decent price depending on condition.
I take back what I said about the one on the right being a marker light it apears to have a switch in the stem which would make it some kind of interior light. Tim
