Light unit

A Lucas light unit from the A.C. magneto direct-lighting electrical system, cataloged 1963-1967.

PN · 54520452

This is a Lucas light unit, listed in the electrical equipment section of the parts books alongside the A.C. magneto ignition coils, wiring harness, and direct lighting setups. It shows up across catalog entries running from 1963 to 1967, tied into the direct-lighting electrical system rather than a battery-charging setup.

A light unit in this context is the lamp assembly itself, the piece that houses the bulb and reflector for the headlamp. On these direct-lighting magneto systems, the lighting circuit runs straight off the alternator rather than through a battery, so the light unit and its wiring are part of that whole magneto-and-coils arrangement covered in the same figures.

We don't have more detail on this one beyond where it sits in the catalog. If you're chasing this for a specific machine, call the shop and we'll confirm fitment before you order.
