bought a pair of extreem whites for the high beems. installed them and there was no difference from the stock bulbs. I returned them to the place I bought them, and purchased another pair someplace different. I installed them. The second set seemed brighter but still had the yellow in the beem. If there is anyone out there who has these bulbs or had them can you please give me some feed back. I need to know if this is normal for this bulb or if I am just having some really bad luck. Also, if any one has any suggestions for alternative bulbs it would be greatly appreciated. Thanks!!!
