On my 33 I replaced attwood 2nm stern lights with 3.5 in hella warm white leds and also installed warm white leds under the gunwales. The hella's are courtesy flush mount leds and run about 30 bucks a piece. The rope lightoing is from imtra and you need to buy a little more than whatever l;ength your are going to use plus you need to buy the grey thick wire connector for it as well as a butt cap for the end you do not connect. The best thing to hold the rope ligthing up is small short screws screwed into plastic conduit clips. The courtesy round leds fit in the hole and basically the same footprint that the attwoods do, but the attwoods have two screw holes, one at top, and one at bottom, where as the hella leds have 3 spread evenly apart so u will have to drill new holes. I just put 5200 in the old holes for the hell of it and drilled new holes. For wiring just snip the old attwood wires close as u can. Slide rope led and hella coutesy led positive lead into the same end of a heat shrink butt connector, do the same with the negative leads. Crimp that side then place the old wire leads coming from the power source into the appropriate ends of the butt connectors. Crimp an dheat shrink both ends. Screw that bitch into place and flip the switch on and hope u dont have to touch any of that crap again. My way is easy but you probably want to match the color of the lighst since they both operate off of courtesy light switch. Do not use red leds or blue leds on either rope or courtesy lights for cockpit. I thought about blue, but the cockpit is a place whhere you need normal lighting to perform duties for fishing. Look at any custom battlewagon out there. Many have cool blue led or green led lights on the bridhge and hardtop and tower. But the spreader lights and cockpit lights are all white. There is a reason.
