The wattage on the OEM are 65W for the high beam and 55W for the low beam. Check out the link below. This is the package that I purchased.Where can I look to see what my wattage is? I bought a G6 GT yesterday and want to do the Hi/Low/Fog bulbs right away. There's one on this page now that links to Ebay and has 3 sets of 8500K Blue Xenon H11 and H9 bulbs that would fit my car. Hesitant to spend $50+ on bulbs like these as i've had some in the past on other cars burn out regularly, and that's with me being carefull not to touch the bulbs. Wattage difference maybe?
