Internally Powered Speedometers
Internally powered speedometers use a replaceable battery to power themselves. They do not require any power wires to be attached to the vehicle they are being used on. They automatically turn on when in use and turn off when they are not being used. The battery in these type of speedometers lasts a long time and rarely needs to be replaced.
Externally Powered Speedometers
Externally powered speedometers use an electrical signal from the scooter or bike to power themselves and control the speedometer and other functions such as turn signal and headlight indicators and battery power gauge. These type of speedometers do not have or require an internal battery to operate.
