2003 Mustang GT Rear Bumper lights

I bought some clear bumper lights for my stang and i need to take out the factory ones. I didnt notice before but there are no screws on the outside of the lights holding them in. How do you take the factory ones out. Somebody told me to just pull them and they will come out but i do not want to risk breaking them, he isn't a very reliable source of info anyways.

Also on my friends 1988 Bronco Custom his cruise control quite working. How can we check the problem and get it fixed ourselves.

Your tailights have nuts you need to take off from inside the truck. Take the carpet of the backside of your trunk you'll see em.

When i said bumper lights i should have said the red reflectors on the bumper itself. Can i get to these thru the bumper as well?
