AVY 14...what you are quoting are posts from "WBH" specific threads...that is to say you are/were looking at posts related soley to the "Without Body Hardware" or "Without Cladding" Avs.
Those Avs...known as "Avarados" or "nekked Avs" or "Avs without pants" are completely different in several aspects...including lighting, fenders, grills, bowties, etc.
Now then...it appears you have a Cladded Av...also known as "the original"...so make sure that in the future you do not relate "mods" designed for "WBH specific" with the Cladded Av...
Stock Fog lamps on the cladded Avs are 27watt as mentioned by 805dre...
an Excellant engineer who has Excellant advise...but with all due respect...some "by the book" advise has practical solutions that are NOT "by the book"...or what I endearingly refer to as
"Tactical to Practical"...
I will ALWAYS LISTEN & RESPECT what 805dre has to say...and after some thought on the specific issue
I may decide to make my own choice realizing the potential consequences of my decision to ignore the educated advise of "The Man".
Having givin you this disclaimer...you have some options regarding fog lamp bulbs for the cladded Av which I'm positive will cause 805dre to

and disapprove of...
Option one: stay with the dim stock 27 watters
Option two: change over to the 37 watt Sylvania 893 Silver Star...but...know that they have been a HUGE PROBLEM because Sylvania has a production issue that affects the bulb life and they are not lasting more than a week or so at best...I DON"T LIKE THIS OPTION until Sylvania improves the bulb...rumor has it they are...but it is NOT AVAILABLE yet...
Option three: change over to 50 watt Sylvania 885 halogen...BRIGHT, have had ZERO issues, replaced my failed 893s with these; they are brighter and been in for 8 months now...NO ISSUES...BE WARNED ABOUT 50 WATTS...THERE HAVE BEEN REPORTS OF MELTED HOUSINGS DUE TO THE HEAT PRODUCED BY THEM, but my research on this site shows that to be 50 watters that were installed on the WBH models that have a different and more shallow housing.
There are other options...but I will only give you what I have had experience with...and for the Cladded Av as of this time frame...the 50 watt Sylvania 885s are the way to go...
