12V power side question in a 2005 2720 Trailmanor

[coralcruze]

Does anyone know if the 12V electrical side on the 2005 TM is AC or DC current?

Any issues or special consideration I need to install new LED patio lights? I am also considering adding an LED light strip to be powered on the same circuit and switch as my patio light is on.

I plan on upgrading to the following lights:

Anyone have any expierience with these or installing similar lights?

Thanks in advance.
