Bulb was worn out and broken open
The unit is a press fit. To remove the old one required breaking the plastic compression tabs that hold it in place. That was simple enough. Replacing requires lining up in the correct position to meet the inner hose. Then push it in. The compression tabs on the replacement click in and hold.in place.
