1- The vent must be pulled out. A wire with a hook in the end works (like the cluster-pulling tools) to pull on the vent.

While pulling, you need to release the four clips, two top and two bottom, visible inside the vent. A small screwdriver will pry them inward, one at a time while keeping outward pressure on the vent assembly.

The bulb holder is pressed/clipped into the back of the vent assembly.
