Headlamp Harness
Lucas headlamp wiring harness, PN 54960724, for Norton Commando Fastback, Roadster, Interpol, and Interstate models.
This is a headlamp wiring harness carrying the Lucas part number 54960724, built for the headlamp shell on Norton Commando models. The catalog record ties it specifically to the Fastback, Fastback L.R., Roadster, Interpol, and Interstate variants, which tells you it's the harness that lives inside the headlamp bucket and handles the wiring runs to and from the light itself rather than the main frame harness.

On these machines the headlamp shell doubles as a junction point, so this harness is the piece that connects the bulb, pilot light, and switch feeds inside that shell before they tie into the rest of the bike's electrics. If you're rewiring a Commando and the headlamp end of things is original or getting old and brittle, this is the specific sub-harness you're after rather than the full-length loom.
Worth being clear about: this is a Norton part, not a Triumph one, even though it shows up in a Lucas-numbered system the way a lot of British electrical parts do. Our record on it is fairly brief, so if you've got a different model variant than what's listed here, give us a call and we'll confirm before you order.
