Rear light wiring connection on the Breezer Uptown 8

These two buttons are the original connections for the rear light. At least one of them came off every ride. Vibration would make it happen. I love the bike, but those connectors are engineered to fail. And it's the rear light, so it FAILS SILENTLY when I'm in traffic at night. Not that all rear lights don't fail silently -- just don't ever rely on a single one. Not that all the lights and a bright reflective jacket will make motorists "see" you.
