How to select an item inside another item

I modeled a light fixture which has an outer container and the bulb on the inside. I need to assign an emissive texture to the bulb and a brass texture to it’s base. However since it’s contained inside the housing, when I click on it it just selects the glass of the housing that surrounds it. How can I select the bulb itself? Thanks.

Hi there! If the bulb is an individual model, you can select it at the resource list!
