Question
Need to replace the third brake light on my ES300 2003.  Bought the bulb, now what?  Thanks.

Answer
First get into the back seat. Grab the center stop assy with both hands. 1st step.slightly slide the assy to the side of you're left hand. 2nd step. rotate up, the edge of the assy that is farthest from the the rear glass. 3rd step. Lift the assy up and out.next pull out bulb and install new one. Next install in reverse order. It sounds easy but its a little tricky. Good luck marilyn
