I didnt know where else to put/ask it.

My boat has those lights with a switch on them. I wanted to get some bluewater LEDS, but do they have a switch and can I wire them into the current light? IE remove that light and wire the bluewater in place of them?

I didnt see if they came with a switch on the site. Or would I just leave that light in? The thing is that if I leave that On it WILL drain the battery...Thoughts.
