[El Sol Infinito]

On my '64, There are some real electrical issues with my dash, so I have some questions:
1. What are the three circular lights flanked on each side by a toggle switch? This is located just under the clock. What do the toggle switches do? I think one is marked D and the other F.
2. There is a long rectangular red plastic light lens at the bottom of the console. It seems to push in and out. What is this?
3. I have the AM radio that actually works (sounds great). How hard is it to retrofit the AM/FM unit? Anyone have one they want to sell/trade?
