Horn (Type 8H)
Lucas 8H horn, PN 70163, listed in mid-1960s headlamp and wiring harness electrical figures.
This is the Lucas 8H horn, part number 70163, as listed in the electrical and headlamp sections of the parts books it appears in. It shows up alongside the nacelle, headlamp, wiring harness, and switch assemblies, which tells you where it lives on the bike - wired into the front-end electrics rather than tucked away in the primary or gearbox area.

A horn like this is a simple electromagnetic unit: current from the switch energizes a coil that vibrates a diaphragm, and that's your warning signal. It's a wear item mostly in the sense that contacts inside can pit or corrode over the years, and the mounting bracket can crack or the wiring can go brittle.
Our catalog records show this part across several figure listings from the mid-1960s. If you're matching this up to a specific machine, check your parts book figure against what we've got here before you order, since the description alone doesn't pin down every model it was used on.
