Headlight Fog Removal

Does anyone have an effective way of removing headlight fog? I just picked up my Tacoma a couple weeks ago and would like to clear the fog from the headlight covers without replacing the whole assembly. Any/all advice is greatly appreciated! Thank you!

 

I used the 3M kit on my mom's old Buick. It worked for a while but it seems that if you don't regularly put UV protectant on them they fog again pretty quick. Luckily she traded that car in for a Camry.

Based on that expereince and the fact that mine are more pitted from sand, etc. I'll probably just replace them with OEM lights. Expensive, but reading multiple posts on here and other forums, none of the aftermarkets seem to reliably hold up as well or work as well.
