er sorry for the stupid question

... if i change my headlight bulbs to a higher wattage bulb, will i fry the harness? stock wattage is 51 i think. i have been using some nokya yellow bulbs (70w) for more than a year and they looked great + better visability. i decided to switch them to some hyper whites because they attract to much attention.

(they are a lot more "yellower" in person)
i got some cuzo hyper whites and they look great when they are on. the bulbs say they are 80w but they have the same voltage as stock (12v). should i be worried? thanks
