My bow running lights (red and green) and anchor light on top are wired to separate switches and operate independently
That takes up space. It may be fine for you?
But in some boats with rocker switches that take up more room, switches are at a preium and 2 switches to run those lights are not what you want.
Lets take a 8 gang Horizontal Blue Seas panel for example....
This panel is 9 1/4in wide. It comes with All OFF/ON switches Only.
But by buying a DPDT
The first switch in the panel can be changed out and that free's up the 2nd switch to turn ON/OFF something else beside's the Anchor light.
I've seen them both ways.
