General question about wattage and bulbs.

I have heard the warning to death about using higher rating bulbs in the stock harness.

my question is i have set of Nokya Yellows, that i am dying to get in there, but they are 70w/80w,

over our 55/60w.

will the 10 Watts in winter really make a killer difference?

 

I know the houseing should hold up fine, but no idea on the harness.

I have heard of people on 100watt bulbs. With no problems, then again some people totally mess there stuff up (possibly has to do with the type of bulb)

You can upgrade the harness and get brighter light becuase of it, its not too much trouble.
