If you don't mind looking like a total dork a head lamp is the best way to see. It points where ever you look. How handy. Any of the cheap Chinese ones work just fine. I've used a few and not had issues.

If you want something on the bike, the flashlights with mounts work best. Again anything Chinese is just fine. 18650 battery is the nicest size imo. Rechargeable is a must.
