I recently upgraded my lights for mountain biking (wanted brighter/lighter) and have two commuter headlights to get rid of. If interested drop me a line at mboyd50(at)gmail.com.
1. Jet Lights M6 bar mount with charger. The battery doesn't hold much of a charge so this one will require service. Free to a good home.

2. Blackburn System X with bar mount, charger, helmet mount (not pictured) and instruction manual (not pictured). This one works well, just not great for off-road riding. $15 or trade for roughly equivalent value red blinkie.
