Yep, those tiny leds. As I wrote earlier, I received these leds with untwisted leads, resulting in handling them being a nightmare. I tried twisting the leads myself, but that was rather unsuccessful, the leads being too "slippery".
Like you did, I planned my lighting scheme, but I have the disadvantage of having (ultimately) a partly open deck and hull, meaning I have very little room to play with. That's also why I have to route all wiring in an area which will be covered by planks and even so, I was forced to implement a cable duct into the design, for visibility concerns. Since this is a first to me, I'll have to wait and see what the effect will be, once the hull is completed.
The partly open hull is also the reason why I cannot copy your method of two separate leads.
What I did follow though is your method of parallel connecting the led lights.
Still a lot to do before I can declare success.
Thanks for your very extensive explanations, although I can't implement all your ideas, there's still a lot to learn from your approach.
