OK men, thinking caps on. Ready? Here we go then...
In the pic you will see the bows of Deep Quest, and the two viewing ports....I need to get some form of lighting to shine through the ports, be visible to a depth of five feet or so, to be able to run off the rx battery pack (4 x 2900a/hr nicads) without draining it too hard and to be able to be switched on/off from a servo controlled microswitch.
Suggestions or ideas (in plain English please....no techie stuff

) will be gratefully received.
Oh...and it needs to be 100% waterproof as it's in the free flood area of the hull.
