what size led will replace the stock bulb in eatc

[tery]

I saw what someone did to the face plate in their sho eatc and I want to do that. Mine is gen 2 93, It has little bulbs with two wires so I'm thinking I should be able to put in two lead led lights in their place. Please see attached photobucket and tell me if you know about this stuff which ones to get//thanks in advance,
Terry
