take 3 leds …. with a 33k resistance > all in series
place them strategically within your boats interior
and check wether or not your intensity is right or too low
because you can easily reduce the resistance
to make them brighter
since if you would be having a 100 ah battery ….
this power would be lasting a million hours !
cover all metal parts with a poly urethan varnish
for the prevention of any corrosion …
