I think i wasnt sure which way i wanted it exactly, but i thought it might be cooler if parking lights had to be on so that I didnt leave it on by accident. But I agree that it is safer for the electrical system if i just tap the 12v source from the battery.
Do I need a fuse off the battery to prevent any additional current than what is safe for the lighting system (wires and harness) or is the supplied relay sufficient.
