Default PIAA Ion Crystal fog light bulbs keep blowing a fuse, what's wrong?

I just tried to replace my stock fog light bulbs with a pair of PIAA Ion Crystal H3 bulbs I bought from TT-Stuff and they immediately blow a fuse. What's up? The OEM bulbs are 25w and these PIAA's are 55w, which is a large jump but I have seen plenty of you all running these, any and all ideas welcome.

Default I think you answered your own question...>

putting 55W bulbs in a system designed for 25W will do it every time.

yup, rather have a fuse go than have an electrical fire.

Default So are all of the fog light bulb upgrades bunk?...

Tire Rack, TT-Stuff, PIAA, etc all list the 55w bulbs as a direct replacement for the fogs, so what gives?

Default H3's are H3's, sooooo....>>

Yeah, they are direct physical replacements but if the bulbs that came out of there were 25w, I sure wouldn't put 55w ones in unless you want to melt some things...

Also the headlight switch is a weak link...More than a few cars have burned to the ground from a fault there. Sure you want to take the chance since this mod is purely for looks???

Default you are the reason I carry an extinguisher in my TT.

Its a shame if this happened to anyone, but especially you. You took care of that car pretty well.
