Just a quick note from another Sube owner...just finished the H11 to H9 conversion on my 2009 Impreza 2.5i using Veneer79's easy to follow step by step instructions. What a difference! The low beam lights actually light up the road now and I can see things far enough in advance not to run over/into them at night. No problems with getting flashed so far so I assume all's well from other drivers' perspectives. Happy, happy, happy with the conversion * used el cheapo generic H9 bulbs from Crappy Tire - total cost $18 and 10 minutes of my time.
