CONNECTOR,SINGLE WIRE(EA)
A Lucas single-wire bullet connector used in harness and headlamp/switch wiring, sold individually.
Part number 900288, also cataloged under the older C311 designation, is a single-wire bullet connector out of the Lucas electrical system used on Triumphs of this era. It shows up in the wiring harness and headlamp/switch figures, which is where you'd expect it — these connectors are what let a single wire be joined or separated at a lamp, switch, or harness junction without soldering.

If you're tracing a fault in your headlamp nacelle or rebuilding a harness from the switches back to the tail lamp, this is the kind of small connector that tends to corrode or crack with age and cause more grief than the actual wiring does. Cheap enough and small enough to keep a handful of spares in a drawer.
Sold each, so figure out how many junctions you're dealing with before you order.
