my left reverse light is fogging up. what shall i make of this?

 

Its getting moisture inside from somewhere.... I know with headlights you can put them in a oven for a short time, but maybe take it apart and disconnect everything and use a blow dyer inside it or something... maybe someone else can assist

 

should i jsut let the dealer know come service time? i'm about 3000kms till service.

 

yeah if its still under warranty let them fix it just my thoughts..
