Tail/Brake/Turn Light Replacement with LED Lights

[OurJayco]

I have been researching this forum to find information on what bulb is needed to replace the tail/brake/turn lights. The picture below is the tail lights on my 2013 Eagle 314BDS and I am wondering what bulb number I currently have and what bulb number I need for the LED replacement?
I read about "Fast Flash", "Slow Flash" and all other details, but I am only replacing the tail light bulbs on the TT and not on my TV.
Can one of you fine folks tell me what bulb number this fixture currently has and what I need for replacement?
Adding a link or model numbers would be fine.
I don't have the TT now, otherwise I would take the lens off and figure it out on my own.

The bulb that you have now is a 3157 plug in type bulb
