Headlights turning yellow

[NRA95]

Hi everyone. Just wondering whether there is a solution for headlights turning yellow. I know it happens when it’s exposed to the sun. Will the 3M sticker prevent it? I don’t want to put a cheap sticker & ruin my headlights. Only thing is the 3M sticker is priced at Rs.7400. My vehicle is a Perodua Axia (Facelift model) & I park daily in the hot sun. And my headlights are positioned in such a way that it’s severly exposed to the sun. So I’m really looking for a solution for this. 

Thanks in advance!

Park in the shade. the tint film can reduce , but will not prevent or reverse sun exposure.

Invest in a car cover.
