Anyone know how to access the taillight bulb on a 2000 dodge ram ,just blew out need to change thankx.

There should be two torx head (I've also seen phillips, but rarely) screws on the inside of the tailgate opening by the taillight, remove them, grasp the taillight housing and pull towards the back of the truck. The bulb sockets are on the back and twist in the usual manner to remove them from the housing. Change out the bulb(s), align the 2 pins, push the housing forward and re-install the screws.
