Never put both the low or both the high on the same relay / fuse  
circuit. If you are going to install a relay and fuse then you should  
set them up left and right. That way if something happens  you will  
still have a light.

With all this discussion about installing fuses and relays in the  
headlight circuit. The question is how many have had a major short in  
the headlight circuit that has burned up the wiring harness. I  
personally  have been doing this for the last 35 plus years and could  
probably count them on one hand.

So why go to all the effort for something that is not going to be a  
problem and if it is then your harness was probably crap to start  
with. Unless you just want to make some work to do on the car.   
Personally I would rather be out driving.
