[A/S] 12 volt lights

[AirstrmCamper@xxxxxxx]

Hi All
 
I will be replacing the two  ceiling lights in my 79 Center bath Sovereign. I 
will keep the lens and main  frame, but wish to remove the 12 volt 
incandescent bulbs. I would like to put  two 12 volt Florescent lights around 15 " long. 
I will use a Rotary switch like  it has now to control them. The question is, 
does anyone know of a good source  for the some basic lights, no need for 
lens? Thanks
