I know most of you recommend the Sylvania Silverstars. My first question is are the PIAA's better if money is not a factor? My second question is I have seen offroad use only bulbs. The standard buld is a 9007 with wattage of 65/55. The offroad bulbs are 9007 with 100/80 watt. Anyone have any experience with the higher wattage bulbs. And can the factory wiring handle the extra draw. Thanks for your help guys.
