I've had to replace the low beam halogen bulbs 4x in the last two yeasr. these bulbs are not available in the aftermarket auto parts stores....have to purchase from local dealership. they never have these bulbs in stock, always have to order and usually takes 3-4 days. just replaced both the left & right on 01/26/15 and the right bulb burned out again yesterday 4/26/1/5.....exactly 4 months.....not acceptable kia!!!! the parts manager told me that they've had problems with this happening not only in the amanti, but in other models as well. so far both bulbs that were replaced on 4/26/15 are still working.
