Send the H4 back for sure. It will be terrible. If you want quality light upgrade the halogens or do a retrofit.I ordered these 9012s for $69 - http://www.xenondepot.com/9012-Xtreme-LED-kit-p/xt-led-9012.htm
Great quality and puts a ton more light out on low beam. High beam is only slightly better, but the low beam spreads the light to the sides and fills in the details so much more than stock. So impressed by the quality that I ordered a set for my wife's Volt and my motorcycle (H4).
No affiliation with the above. Just a happy customer. Fast shipping too.
