H4 bulbs 100w legal or not????

gettin some new bulbs for my NC30, stock is the H4 60w, but i've seen 100w bulbs on ebay tho they say they're just for "shows".
i want brighter lights, but can't run to HID kit, so why are the 100w not road legal?
i don't mind ahem bendin the law a little especially if it means i'm easier to see... would there be any probs using 100W ie overheating etc?
otherwise what make of 60w h4 bulbs are reccomended?

100w bulbs

There may be a problem with the wiring on your bike being able to handle the extra current and the charging circuit might not be up to the job of running the bike under high electrical loads with the lights lit (ie it might drain the battery if ran at night and cause ignition problems).

They are illegal

but only because there is a rule stating something along the lines that you are not allowed to fit light s of a higher wattage than the origional manufacturers for that vehicle.

I have always fitted 80/100 H4 in the past (cars and bikes), and have never been pulled, or had it commented upon at MOT's so I wouldn't worry too much.

where the high beams are independant of the dipped i have only up rated them, as when you are on dipped beam chances are other light sources are about anyway. It is really just about not taking the piss.
