The headlight went out on my Husqvarna snowblower. There was a P/N for the headlamp but not the bulb. I matched it up to a #889 automotive foglamp bulb by looking through a miniature lamp catalog I found. Maybe this will same someone from buying a $50 headlamp instead of an $8 bulb.

BTW - A manual for an earlier model lists the Husqvarna P/N as

532 40 16-20 for the bulb.
