Hi Bill,
What year is your T2363? And are you looking for inside lighting or outside DOT (stop, turn,clearance) lighting.
If it is most likely a mid 90's to 2007 Sunline, the inside lights were 921 incandescent wedge base bulbs in most cases.
My 2004 camper has them like this on the inside. There are various types pending where they are used.
Some of the new LED's next to the old incandescents.
Over the table and on the wall bulbs. The fixture
The LED bulb
Ceiling general lighting in the old bases
Over the bed flood lights
Here is a link to some of newer ones where I bought mine. We got the warm white (3000 kelvin) They are a lot cheaper and brighter now then we we bought ours many years ago. (now 11 years) I can state the quality from these folks is good and I yet have to replace one.

Hope this helps
