Rear deck PENKO light, 92 Esprit, Question

[Thor]

I have a 92 esprit. The rear ski deck Perko light was not working and I decided to pull the assembly apart. There was no light bulb inside the assembly. It is one of the cylinder shaped light bulb with the tip on each side. Does anyone know what spec bulb I need to purchase???

Sylvania 6411 is what I used. 41mm festoon type.https://uploads.tapatalk-cdn.com/20180527/fd7a54ab2f53ac2acd93c5bf1377f3e0.jpg
