The actual "fog light" is just a housing....no need to replace unless it's cracked or broken.....I would take them out and take them inside and get all the water out I them If there is any. Check your voltage and replace the bulbs. If they did like my f150 headlights did you have a mess to clean up!! Lol, when I got water in my f150 fogs the bulbs exploded in the housing...
