Re: LED lights
The "RGB" strips are just that. They are interleaved RED, GREEN, and BLUE LEDs are they are intended to be used with a controller that will vary the power to each of the three colors, so you get "disco" or "mood" lighting effects.
For general purpose lighting, that's a waste of time and money. Buy warm or cool white LED strips, and you can buy those way cheaper on eBay as well. Water-resistant and waterproof, check the listings.
No, none of these are voltage regulated. They are all designed to run from a "12" volt supply but they should be fine on "ships power" with the engine running as well. No twelve-volt regulated strip would work well on a battery supply, as even a (relatively) expensive low-voltage-drop regulator would require feeding them from close to 13 volts all the time, so ignoring the regulation issue is a practical way to go here.
I have run them as under-cabinet lighting in a kitchen, and after a year they still look & work fine, fwiw. Powered by a cheap "12" volt brick, with no testing to see what it actually is. I call it disposable lighting: If I have to replace it in five years, at these prices that's OK too. It is NOT anywhere near as bright as fluorescent tubes or other dedicated large bulbs though, it is nightlighting or mood lighting.
