9003/H4 Silverstar bulbs are indeed High/Low beam! :Dhttp://
www.sylvania.com/auto/silverstar.htmYou can see the chart there that for the 9003 bulbs the wattage for 'em is also: 65 for low, and 72 for high beams.Replace the single bulb for your Vibe and you are set. Matrix owners have seperate high/low beam lights, I believe.
