H20 in headlights

I want to upgrade my headlights,they are to dim at night. I noticed a bit of moisture inside drivers side headlight ass.

Will this effect headlight performance? Worry or not to?

Should I replace/fix the entire headlight assembly?

Where to buy new assembles?

I just noticed the same thing with my 08... Anytime there is condensation in the light assembly, its not good. I recommend replacing them. I found some on ebay pretty reasonable. As far as the lights being dim, DONT waste your money on expensive bulbs like piaa or something like that. Save up a little $ and do a HID conversion. Night and day difference. You will be able to see road signs a 1/4mi away clearly. Expect to pay about $150-$200 for the kit including install (unless you do it yourself)
