just install some piaa xtreme white h4 yesterday to my 96 base 4runner, its alot whiter and brighter than the stock bulbs, sorry i dont have pics of it, but the bulbs are a great improvement to me.
piaa's are definately whiter than stock and very different than silverstars, its all a matter of preference. i was just inpatient and couldnt wait for silverstars to come in (2 weeks during the time when i needed new headlights) so i bought whatever was in the store which were the piaas
the PIAA are nice.. I had them on my old car... I now have the Hella H4 Xenon Blue... they are much brighter and whiter than the PIAA and the SilverStars... I love them
