Which made a lot of sense until I stopped and wondered "do these things have a ground pad or wire?", and I don't think they do? So the question- do they? I don't mean for the input, but rather for the output to the F0 headlight (or other) functions? Thanks in advance!

I didn't see a link to a sample install on your website- might you have one by chance? Im just curious to see if I'm reading your circuit correctly in terms of diode arrangement etc... No sweat if not!

Use Ctrl+f and use key words 'LED Lighting' on my tips page, you should find some topics of interest.
