can somebody help guide me into changing my hatch brake lights- i purchased the buld 921 from Napa auto parts- i managed to remove the decorative frame around the top of hatch by forcing it out- but unable to remove the actual compartment- i am afraid to force it out and it is all plastic and may damage tha clips that hold it together- is there a way of just pulling it out so i can replace ghe bulb- pl adv- thanks
