The low beam light bulbs burn out very often because the melt. Then once you replace them it is hard to get them in the correct position for maximum lighting. The bulbs we have in now are so dimm we have to use the high beams most of the time at night and the on coming drivers flick their lights at us, but we can't see without the high beams. This bulb burn out has been a problem for the whole time we have had the suv.
