The Green Knob

The Original Green Knob simply disconnects the battery to prevent theft--and battery drain.

The Fused Green Knob features a fused bypass wire that allows low-amperage devices to continue operating when the Green Knob is removed. If a thief tries to start the car, the starter's extra current will simply blow the fuse. Fuse can be removed to prevent battery drain during long-term storage.
