1999 Lexus 300 ES replace middle brake bulb
I would think there are screws to get the lens out to be able to change the bulbs. Look along the edges of the lens.
Grab the whole light Assy, and pull it forward, and it unhooks from the rear window base plate, then it just lifts up and out. Small hands help. I changed mine not long ago. Put a LED bulb in and it makes a big difference.
