They sell a black film, just like the yellow film that I bought. Same price, $15. I thought about those too. Ive debated on blacking the car out, but I like the contrast of color.
The car has LED fogs, and they are junk, since ive owned the car, Ive turned on the fog lights on once, and couldnt even tell a difference. I had to double check they worked when I got home.
Ive thought about doing the HID fog lights they sell, but I cant say I care that much since it has HID headlights.
