Taillights

The term is used to let others know when the production is finished for the day, the equipment is packed, and everyone is in their cars, driving away (and their taillights can be seen). Insider lingo.

The Shoot

Refers to when one or more persons get together with a camera, with or without audio, with or without talent, props, or other resources, to film any subject for a project.

The Wrap

Everyone is done shooting for the day and begins packing up.  The day is not done until Taillights.
