HEADLIGHT RIM 7IN LUCAS
Chrome Lucas 7-inch headlight rim that secures the lens over the headlamp shell.
This is the Lucas 7-inch headlight rim, part number 553248, also seen in older records as WW19015 and superseded from the earlier 99-0692. It's the chrome bezel that snaps over the front of the headlamp shell and holds the lens and reflector unit in place, showing up in nacelle and headlamp figures across a wide span of Triumph catalogs from 1960 into the mid-70s.

If your rim is dented, rusted through, or just missing off the front of the bike, this is the piece that replaces it. It's a trim and retention part, not a wiring or bulb component, so swapping it doesn't touch anything electrical behind the lens.
This rim turns up across a long run of figure titles covering different nacelle and headlamp setups, so before ordering it's worth double-checking against your own parts book or the shell you've got, since Lucas 7-inch headlamp hardware was shared across a lot of British makes.
