Washer
A washer used across several Triumph electrical assemblies including headlamp, wiring harness, switch, and ignition coil setups.
Part number 137499 is a washer that shows up across a run of Triumph electrical figures, from headlamp and wiring harness assemblies to the A.C. magneto ignition coil and direct lighting setups. It's a small hardware piece, not a headline part, but it's the kind of thing that keeps a terminal, switch, or fitting seated properly in these electrical assemblies.

This one appears repeatedly across several different figure titles in the catalog, which tells us it's a common washer used at more than one point in the electrical system rather than something unique to a single component. The catalog doesn't spell out its size, material, or exact placement beyond the figure groupings it's listed under.
If you're rebuilding a headlamp shell, wiring harness connection, or switch assembly on one of these machines, it's worth having a few of these on hand. Call the shop if you want help pinning down exactly where it goes on your particular wiring diagram.
