[Healeys] Light Circuits

[John Trifari]

Dave--well said.  I had nothing better to do with my time some years ago so
I put relays in the headlight circuits of my BN1.  Too much wiring; to many
places for things to go wrong, so I pulled everything else and re-wired the
car as per the original.  John Trifari  Golden Gate AHC/BN1

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.
