They are a little bigger than standard type, and would most likely be located on top of the A frame, near the body of the trailer, probably under the LP tank area.
If your trailer has Corning curved windows, no jalousie windows next to the door, and the windows have a chrome-looking trim around them, you almost certainly have a '68. Which is what the serial number pictured above shows.
