Also WTB underwater transom blue LED lights(2), blue LED interior lights(5), and 2 blue battery boxes. If available, looking for 3 blue small grab handles (4"-6").

Look up Boattronics. I use Dan for all my stereo and dash items like Gaffrig, GPS, etc. He should be able to help you out with everything on your list.
