Light unit (99-0686)
Lucas 7 inch headlamp light unit (reflector and lens assembly), PN 516798, supersedes 516812.
This is the Lucas 7 inch headlamp light unit, PN 516798, the reflector and lens assembly that sits inside the headlamp shell and takes a BPF bulb. It shows up across a run of catalog figures covering headlamp, wiring harness, switches and tail lamp setups, including entries specific to the T90, T100SS, TR6, T120, TR6R and T120R headlamp wiring figures, so it was a common replacement unit across a wide slice of the lineup through the 1960s.

The part carries an older factory number, 516812, which this one superseded, and it's also known by the WW11056 form if you're matching against an older parts list. If your headlamp lens or reflector is cracked, clouded, or the silvering has gone, this is the unit you're after rather than trying to source a new outer shell.
