check out my ride...mine is the 05 le JAPAN sedan which had removable fog light covers. i bought some OEM yota lights off of ebay for a total of $150.
i went to the dealer to find out what all was needed and here is what you had to get to be stock:
a new light/turn switch with the fog light switch on it...$250..i think
a relay...$30...i think
and a special type of fuse...$60...again, i think
Sure enough i said HECK NO and went to auto zone and bought an auxillary light wiring harness for about $15 which came with a relay, fuse, clamps, splices...everything.
I used the switch i had bought for my Supercharged 4runner and it popped right into the little square holes that you will find on about ANY toyota.
TALK ABOUT SAVING MONEY

and I can turn my lights on anytime I please...as long as i dont forget to turn them off!
