Another Headlight Question

[kenc5]

While at Bloomington Gold, I bought a set of Euro Designs' 9005/9006 and 893(fog) bulbs. They looked a lot whiter than the existing headlights. Now the question: Is there a problem putting 100 and 80 watt bulbs in the place of 55/60 watt bulbs? Will the harness fry? Should I worry at all?
Thanks for the help.
