I would love to improve the lighting for my car and those H9's seem to be getting fairly good reviews, but are there any bulbs that are significantly brighter that don't require any cutting or modifying the oem setup like the H9's? I'm just wondering, because I am afraid that if I get the H9's and perform the required modifications, then will that potentially limit or affect my choices of other bulbs or lighting options if I decide to move away from the H9's??
Side note, what exactly are the model #'s or style of bulb used for the low beam and high beams for a 2011 WRX?? As in, how do I know if a bulb is of proper fitment if I go to a store to buy replacements or different bulbs?? Sorry, nooobie when it comes to bulbs :P thanks guys
