Running Lights: When the switch for the running lights is turned on, both the headlights and taillights will illuminate. This allows for increased visibility and safety while driving. Horn: By pressing the horn button, the horn will begin to sound, alerting others. To stop the horn from sounding, simply release the button. Brake light: when the brake signal line is normally connected with the controller's brake low pressure signal, the brake light will light up when braking. Fitment: Waterproof line lamp set is applicable to 24V-48V electric bicycle, the bicycle tail lamp is easy to install and use, and is a good accessory for upgrading your bicycle. Note: This product needs to be connected to the same battery as the controller, otherwise the braking function cannot be activated. Connecting to the brake requires the controller to be a low-speed brake.
