It's as easy as changing you headlights. Just a bit tough to get to. I did mine while they were up on a hoist.

FYI though...the 2005 fog lamps are the same bulbs as your low-beams - 9006.

 

So there's no possible way to fit them? becuase it seems like the manual says that the fogs are H3's ??hmmm.

 

Check first (pull it out of the socket).
I didn't and accepted the on-line comments that they were H3's. Got home and tried to plug them in only to notice that they were pretty big...9006 big! DOH! Wasted my $$ on useless H3 lamps and sold them for a loss...tho they work in prior Corolla years.

 

I used to have an 04 Corolla S and now an 05 Corolla XRS so I know for a fact that the 05 Corolla S and XRS fog lights are a lot more powerful than the 03, 04s. So maybe the H3s were on 03 and 04 and the 9006 are on 05.

 

yep you guys were right... it is 9006's for the fog lights on the 05 corolla.. thanks appreciate your time and help.
