How do I change a brake light - 2003 Dodge Caravan

I hope you tal about the bulb, right?? whel open your tail gate and on the side of the tail light you will see two phillips srcrew take them out and your tal light will slide right out, then you will see the harneses from the diferent bulbs, find the one that is blown and turn it just half turn and then pull it out, then pull out the bulb and replace it to put everything back together just do the same process backwards, hope this helps.
