Light switch (99-1251)
Lucas light switch (99-1251), cataloged as 34419, from the headlamp and flasher lamp circuit; later superseded by 31788.
This is the light switch listed under Lucas number 99-1251, cataloged here as part number 34419. It shows up in the parts book under the HEADLAMP AND FLASHER LAMPS figure, so it lives in the headlamp/switch circuit rather than anywhere in the ignition or charging system.

The part carries a couple of alternate numbers in our records — 82-0117D and F117D — so if your parts book or an old invoice lists one of those, it's the same physical switch. Our catalog data shows this one tied to a single model year, 1974, though that's as far as the record goes on fitment specifics.
This number was later superseded by 31788, so if 34419 is hard to source, that's the number to ask about. Bring your old switch or a clear photo when you're not sure which version you've got — Lucas switches in this family can look similar but wire up differently.
