Ammeter, type 2AR
Lucas type 2AR ammeter (PN 36296) fitted in the headlamp nacelle to show charge or discharge on the electrical system.
This is a Lucas type 2AR ammeter, part number 36296, the gauge that sits in the headlamp nacelle or headlamp shell and shows whether the electrical system is charging or discharging. It reads current flow to and from the battery, so a glance at the needle tells you if the generator/alternator is putting current back in or if you're running down the battery.

In the catalog record this ammeter shows up across nacelle and headlamp/wiring harness/switch figures, including the T90 and T100SS headlamp and harness listings, which puts it right at the front end of the bike where the headlamp, switches, and harness all come together. It's a small, simple instrument but an important one to have working, since it's often the first sign of a charging problem before the battery goes flat on you.
We don't have a specific model-year fitment beyond the catalog span noted, so if you're matching this to a particular nacelle or headlamp shell, check the diameter and wiring against what's currently fitted before you order.
