Until the massive snow hits ya, I agree with lights and night riding.
I ride year 'round up here, and we don't get a lot of snow, but we get a lot of dark. Short winter days are barely long enough daylight to cover a shift at work (minus the commute time.)
Generator lights front and back. 2 PBSF lights. Lots of reflectors. Helmet light. Cold weather clothing.
