STOP AND TAIL LAMP, Type 679
Lucas Type 679 stop and tail lamp unit, PN 53972, used in direct-lighting (magneto) electrical setups.
This is the Lucas Type 679 stop and tail lamp, part number 53972, showing up in the catalog across figures covering AC magneto ignition, direct lighting, and the stator/tail lamp/stop lamp switch setup. It's the rear lamp unit that handles both the running tail light and the brake light function in one housing.

The catalog appearances run from 1964 through 1967 and it turns up in several different figure groupings tied to the direct lighting (magneto-powered, no battery) electrical system rather than a battery/coil setup. If you're chasing down a rear lamp for a bike running direct lighting off the magneto, this is worth checking against your own wiring and lamp mounting before you order.
We don't have more detail on this one beyond the Lucas type designation and where it shows up in the parts books. Give the shop a call and we can help confirm it matches what's on your bike.
