WINDOW,T/LAMP TYPE 564
Lens window for the Type 564 taillight assembly, part number 57-5200.
This is the lens window for the Type 564 taillight, part number 57-5200. It's the small lens piece that sits in the taillight body so the bulb's light can shine through to the rear of the bike. The catalog lists it under the tail lamp and stop lamp switch figures, along with the headlamp/wiring harness and speedometer/tachometer figures where the tail lamp assembly gets called out.

This one shows up across a long run of catalog entries, going back to 1960 and forward to 1969, so it's a part that stuck around through several years of Triumph production without much change on paper. If you're chasing a Type 564 taillight rebuild, this is the lens window you'd be after alongside the lamp body and bulb.
We don't have more detail on this one beyond the catalog listing itself. If you're not sure your taillight is a Type 564, bring in the old part or a photo and we can confirm before you order.
