IGNITION KEY HEAD LIGHT PRS8 TYPE SWITCH
Ignition key for a Lucas PRS8-type switch, as fitted in the headlamp nacelle.
This is the ignition key for a Lucas PRS8-type switch, the kind fitted in the headlamp nacelle on early unit-construction Triumphs. It's the actual key blank, not the switch body itself, so if you've lost yours or need a spare cut, this is the part to order.

The PRS8 switch lives in the nacelle assembly along with the light switch, and the catalog groups this key under that same nacelle, headlamp, and switches figure. Catalog records show it appearing across 1960 to 1962, but the switch itself may show up on other years too, so check what's actually in your nacelle before ordering.
The alias WW10053 is the same physical key under a different number, so if your old parts book lists that instead of 318341, you're looking at the same item.
