Norton 410 Main bulb 45/40
410-type 45/40 watt dual-filament headlamp bulb with a 3-prong base, PN 06-8019.
This is the 410-type headlamp bulb, the 45/40 watt dual-filament unit that goes in the headlight shell. It carries a 3-prong base and is a standard replacement item for machines fitted with a P45-style headlamp socket. Our catalog shows it appearing in headlamp and flasher lamp figures across entries from 1976 to 1980.

The dual filament setup gives you high beam and low beam out of one bulb, which is how most of these classic headlamp assemblies were wired from the factory. If your headlamp is dim on one setting but fine on the other, or dead on both, this is one of the first things worth checking before you start chasing wiring gremlins.
We don't have more specific model-year fitment on file for this part beyond the catalog range noted above, so if you're not sure your headlamp shell takes this exact bulb and base type, give us a call and we'll confirm before you order.
