Older LS's have a better fog light.
The 98 and newer are cosmetic for sure.
I wanted a set of yellow bulbs for the fogs as they accent the HID's perfectly ,since i need a new right foglight anyway i might as well replace them and use the extra space for the opening of the intake i am going to build.
I alreayd have silverstars in the fogs, no real conceqeunce to outputs .
As well once i try the HIR's i will be able to gauge just how good they are.
Catz lighting makes better products than PIAA by far and are much less known as they range in 300 and up price range.
They can be had for a steal on ebya though.
As i paid almost $500 for my pair 7 years ago and they still have the same catz bulbs and orignal housings and lenses that i bought them with. Try that for any other foglight and they would have alreayd needed replacing by now, belive me i have 8 old set of fogs lying around my house.
Later on i am going to paint the inside of the reflectors on all the front lights to give them a nice smoke effect as it really brings out the front end.
