rocker switch

Hi all, I noticed West Marine now sells a variety of these: I am deciding whether to install one at the dashboard where there is currently a blank. It would seem to be a good option rather than drilling another hole in the dash. * Has anybody opted to go with one of these? * Do you...

The battery terminal (port side) rocker switch does not light in the cabin circuit panel. It does work fine though, but I'd like to replace it. Any idea how to do it? Or is there just a bulb somewhere that can be replaced? Thanks...
