What do you guys recommend me to do? Any input would be appreciated. Thanks.
I know xenon bulbs will lose brightness over time, but I donít think that 3 years would make that much difference. If they did not replace the bulb, then that could not be the answer anyway. More likely, the unbalance you are referring to is because you are comparing the light output through one brand new headlight lens and one that is 3+ years old.

Try polishing the old lens and then compare. There are a number of polish manufacturers such as 3M, Motherís, etc. Try a search on the DIY sub-forum.
