- use the spade connector terminals.
Most shops supply the bikes using the bare wire system. But you can easily use spade connectors. The red size works best. They are available in small electronics stores. Insert the bare cable in from the red end and crimp it using a standard crimping tool. It does not matter which wire you install on which side.
We recommend that you carry a few of these spare connectors on trips in case you ever damage the ones that connect to the back of the headlight.
The red switch on the opposite side of the taillight turns the standlight off if you happen to want to do that when you park the bike.
