      Location: Holland, Tx | I want to do my interior trailer lighting on 12v power. I want them to come on at the flip of a switch (one switch for lights in nose, one for lights over main floor and one switch set up for fan over shower...possibly a light nearby too).  Can these lights be used? I was confused since there is a switch on the light that determines if one or both lights come on? http://www.pplmotorhomes.com/parts/rv-lights/double-dome-light.htm    |
