First of all, sorry for creating another thread about this. I found it earlier and now I can't find the same thread again after searching a few places.
Anyway, I just bought a cheap set of fog lights and was wiring them up when i found the thread on here about using a fuse tap to power them. My question is, if the fuse slot is only powered with the ignition on, do I still need the relay? I suppose this sounds stupid but it made sense to me, it seemed kind of redundant to use both. Thanks
