its really easy...u dont have to take the mirrors off the door but u will have to take the actual mirror out of the mirror holder.
to remove the mirror (glass part) grab and pull out (towards the back of the car) carefully on the bottom of the mirror. there are two clips that will pop off and slide the mirror down and out. its connected by wires so roll down ur window and set it on the window seal.
next you need a philips head screw driver and remove the 4 silver screws behind the mirror.
the front painted cover will still be attached at the point...to remove the cover you will have to pull carefully straight forward (towards the front of the car) to remove the clips. after remove the light is accessible
the bulb used is a 194 bulb
