At my age, I'm way beyond keeping track of how many posts I make in different forums and blogs. The LinkedIn and other business networking sites where I spend much of my time don't even have a post counter. Anyway, lights might be the purpose for on-board electrical for some folks, but not for me. As mentioned a few times above, my need is for electronic gadgets - such as GPS in exploring and shopping nearby communities, plus keeping backup battery power charged up for a laptop computer for business uses (out on the docks and other locations within a large marina).
