Jack.. I also lost the link.... It's amazing to me... A lot of research has proven just what you stated... but they buy these bulbs by the gross... And are "thrilled" with the result!.. In psychology we call this "Cognitive Dissonance." When you spend that much on an item... it HAS to be worth it!!!...I bought some Wagner SuperBrights (or something like that). A little bit brighter.. but then again they were new bulbs and That may have been the difference.. all of $12/bulb... I would love to make our low beams brighter... Anyone ever put the 9005's (for the High Beams) into our low's???... They seem SO MUCH brighter... Ther must be a reason why not.. I just don't know it!!
