i want to change my lights to led lights can i just change the bulbs on my boat or do i have to change the wiring too all the wiring is done on it for regular lights. it's a 14 sea nymph aluminum boat. i know that leds draw less battery power than regular lights that's why i want to change them. or do i have to buy the navigational led light and the sten light in leds too and change the wire gauge too. you's been a big help before thanks
