Leaking Headlights?

My right side headlight is leaking pretty good. Even a light rain will cause quite a bit of moisture on the inside. Can this be repaired by just caulking around where the lens attaches or is it best to just replace the assembly?

 

It depends on how much you want to spend/save/troubleshoot. It could be a small crack that could be fixed easily. It could also be that the rubber boot for the bulb is bad and allowing air and moisture in.

You could scout things out and see what is up and if you can fix it. It means taking the time to remove the light and check everything out. That could mean taking things apart a couple times depending on what you find. Or, you could just buy a replacement and do the removal/install once. It really depends on how much time you have and if you want to mess around with it or just install a new part.
