Dash turn signal indicator bulb

Our '56 has an aftermarket dash cluster with tiny LED bulbs for turn indicators. They are located in the upper corners of the bezel. I have no idea who produced the bezel. I think one bulb may be going bad because it starts flashing in sync with the outside bulbs, but then starts flashing rapidly. The other inside bulb works fine. I know nothing about them, or what to order. They have tiny wires running to them that look like heavy seeing threads. The wires run to a bulb base about 3/16" in diameter. Can anyone give me some help?

I've found what I need.
