How much wattage can stock headlight wiring support?

I did the relay method too. Picked up the stock headlight harness to arm the relay. Routed an 8 gauge wire from the battery to a water proof box containing 4 relays. High beam, low beam, driving lights  and  then electric fans.  Cibie glass and PIAA Superbrights H4s

 

H4

Much appreciated, I’m sure other’s will benefit from it as well.

I may have to come back to this thread.  In my '83 ZXT I am fortunate to have one of the few remaining pairs of Cibie Z-beam headlights, which have a wonderful lens and reflector design. The light is quite good and the distance is excellent with standard halogen lamps.  

I do note that the lens on my Cibies look  almost identical to the lens on the PIAA headlights in post #26.  I've always noticed that on high beams, I can actually see the lines on the Cibie lenses projected onto the road ahead. Therefore, I expect that those PIAA lights work very well indeed!

It probably would be good for me to do the relay thing with the ZX, but that's future business for now.

@Pilgrim that is a cibie glass. Only the H4 is a PIAA.

Well, that explains a lot!  Those headlights are excellent. We are very fortunate to have them - I applied 3M headlight film over mine to prevent rock chips or breakage.
