Ammeter, type 2AR (99-1044)
Lucas type 2AR ammeter, PN 36403, mounted in the headlamp shell to show charging system output.
This is a Lucas type 2AR ammeter, catalog number 36403, also cross-referenced as 99-1044 and 1452-001. It sits in the headlamp shell on bikes so equipped, wired into the charging circuit so the rider can see whether the electrical system is charging or discharging while the engine runs.

It shows up in the wiring harness and switch panel figures alongside the headlamp and tail lamp parts, which is where you'd expect it — the ammeter reads current flow between the generator or alternator and the battery, and a glance at the needle tells you if something's gone wrong with the charging side before you end up stranded with a dead battery.
Catalog appearances put this one in the late-60s range. If you're replacing an old, sluggish, or stuck-needle unit, this is the direct catalog part for it — just confirm your harness and mounting hole match up before you order.
