Light unit
A Lucas light unit (516828) listed with the headlamp assembly on T100C and TR6C electrical figures.
This is a Lucas light unit, catalog number 516828, showing up in the electrical figures alongside the ignition capacitor on both T100C and TR6C headlamp setups. In the parts books it's grouped in with the headlamp assembly rather than listed as a standalone lens or shell, so when you're ordering, make sure you know whether you need the full unit or just a piece of it.

The catalog listing for this one is short on detail beyond where it shows up in the electrical equipment section. It appears across catalog entries spanning 1963 to 1968, tied to those T100C and TR6C headlamp figures specifically.
If you're trying to match this against a headlamp you've got on the bench, give us a call and we'll walk through it with you before you order — the parts book doesn't spell out enough on its own to guarantee a match sight unseen.
