LUCAS TAILLIGHT LENS 564
Lens for the Lucas 564 round taillight fitted to a range of British bikes into the mid-1960s.
This is the lens for the Lucas 564 taillight, the round rear lamp fitted across a good stretch of the British bike world before the later 'beehive' style lens took over. On the parts side it shows up under 57-3839, and you'll also see it cataloged as 573839 or 99-9964 - same lens, different number depending on which book or list you're working from.

It lives in the tail lamp assembly and shows up in the wiring/switch figures alongside the stop lamp switch, speedo, and tach - so it's grouped with the rest of the rear lighting and instrument cluster in the parts books rather than off on its own. If your lens has gone cloudy, cracked, or just isn't sealing right against the lamp body anymore, this is the piece you're after rather than the whole lamp assembly.
We carry it as the lens only. If you need the full tail lamp with the reflector and bulb holder included, that's a separate listing, so make sure you're ordering the right one for what you actually need.
