They run off 6V, but they'd need a dropping resistor, which is normally on the CV board for the LED socket.

John, Your repeating what I said, but it is not on the CV Board in this case.  Looking closely at your picture you can see the yellow connector with red and black wires on the side of the bottom board.  In this case MTH used the PS-1 bottom board marker connection.   You do not have a marker connection on  that CV Board.  You just have 6V outputs.  That is why I said you should trace where the leads go.

For a TMCC conversion where the PS-1 board comes out, yes, you can tap off the CV board.  You can use the LNB or IL plug since these are constant on, not directional.  Solder leads to the bottom pins, but install a 100-150 ohm resistor in line with one of the leads.  Send it back to the pad keeping Red +DC and Blck -DC and you will have markers lite and the ability to remove shell without having to unplug light connector.  G
