Thanks, I think I'm gonna 'just do it' like you said and not worry too much about it.
As for electrolysis, I'll just isolate it with some nylon spacers. But worse case it would be the $100 aluminum light that goes, not the hull (right!?) In any case, it'll be in a place where I can inspect the backside easily.
As for power/heat, these are LED and really quite nice little lights
. I'm also planning on using some as spreader lights
As for the pimpin light... can't help it! I am a redneck and grew up in a trailer park. I have about a billion projects for my boat and so where did I start? I bought some Blue LED speaker grills

I did do some actual work on it though:
