my dc5 has one yellowing/fading light and the other one has been replaced less than a year ago before i bought it due to a small acident, so now i am stuck with one brand new clear headlight and one yellowing one.

i have tried polishing and using a headlight restoration kit on the light but it isnt really helping at all, are there any other ways to clean it? .

do i maybe have to clean inside the lense aswell or will i have to buy a new lense? where can i get a genuince honda lense from and how much are they? i live in sydney thanks-

(one other thing i noticed is that when that headlight is wet like just after i wash the car it looks just as clean as the other one, but as it starts to dry it returns to the yellow colour-(
