Nice report and photos, Tiffany.
An observation about the wire supplied. It's magnet wire, I believe, which uses clear insulation; you can't see the insulation, hence, the belief that the wire is not insulated--it is. I have one of Dave's strips, also, and have deliberately held both wires together while energized and there is no short.
Also, I have a car essentially identical to the one you have, as well as a standard dome, and I plan to attach the strip lighting to the ceilings of the domes. In other words, the dome interiors will be lit directly, instead of from below to avoid the loss of light caused by the translucent "floors" of the interiors.
Thanks, again, for the report and photos.
