I enjoy dabbling in the field of headlights so I'll chime in.
If yours are halogen headlights, the best replacement is a total new unit and not just an LED bulb in place of the halogen bulb. They are different enough that extreme glare and poor performance are common. Legit companies such as Diode Dynamics will explain that LED Bulbs in halogen headlights are not legal for street use. This is why so many companies sell them as fog light bulbs or for off road only.
A good replacement is not cheap. JW Speaker is my favorite because it is a good legal headlight and they make mounting brackets for them. Morimoto makes a Sealed 6 headlight but I have not seen a mounting bracket. Perhaps the factory would work.

this company supplies many factory lights. The only one I have experience with is the factory one on my Thor and it was a dismal headlight. But, they make others in various sizes. We replaced ours with JW Speaker. 5.75 inch. There are many headlight units being sold that are very inexpensive. These are most likely priced according to quality.
