on my passenger side headlight, the yellow lens for the foglights broke off somehow (i got it this way) so it looks white with a bit of yellow from what's left of the lens. is there a replacement for it? any suggestions on what I should do?

 

#1 take those yellow lens out on both headlights. and replace the original white bulbs to blue (like HID) or yellow bulbs. whatever color you like.

#2 get a new set of headlights
