Well, you can't electrocute yourself with your 12v car, but you could maybe get a nasty burn.

I'll look at the video later - building a tank tonight.

The only thing I didn't see you mention is how to address the dimmed Halos with the DRLs on. Is there something mentioned about it with their controller ?
And by pulling the DRL fuse, are you taking half the power away from the Headlights ? As I mentioned earlier on, some cars are designed with 2 powered circuits. The first is half power, which you understand. The second is full power and is how your headlights go from DRL to Headlights.

This is why I was suggesting so many relays.

I'll get back to you after I look at the video.

Looking forward to getting my new mixing tank siliconed tonight !!
