removing fog lights
 

i got water, sand, mud in my fog lights and need to take them out so i can clean and get the crap out to put new bulbs in cause the other ones exploded. i just cant seem to get them out and i dont want to have to take the whole plastic piece the olds them into place cause its a pain. so i was hoping someone knew a easy way to take them out. 2005 gmc sierra z71.
