depending on the lighting insufficiency, often a change in the fog lights is enough to make lighting satisfactory. this usually has less glare risk also, but depending on depth of emitter you can still get crazy glare if a poor design. somewhere there are examples of adjustable depth bulbs in a fog housing.

Will 35w HID kit melt fog lights? What have you tried? - ClubLexus - Lexus Forum Discussion example of focal point mismatch (depth incorrect). the test was to find max potential glare. it was very ridiculous.

sino's (from sinolyn) currently the best fogs OEM Foglights on GX460 - Are They Just 'Decorative', or Functional Add'l Visibility? - ClubLexus - Lexus Forum Discussion but take a special bracket. best as in highest light output. but thats not always best. heres an image of a non dual focus biled, too much light for any use when theres a lot of reflection The very best GX fog light setup - ClubLexus - Lexus Forum Discussion the sinos have dual focus so even though they are brighter, they are better fort long distance, less witdh.

 

Looking to replace OEM bulbs in my son's 2011 GX460 - go with the low beam SL2 or SL2 Pro? Thanks
