Rear brake switch ("frog") for Viper 125-200 cc motorcycles and similar (China, Minsk): when the rear brake is applied, it closes the circuit and turns on the brake light.
Replace it if the brake light does not come on, stays on constantly or comes on with a delay. First check the bulb, the wiring and the connector.
- Disconnect the battery before replacement.
- Check the condition of the connectors and wiring: very often they are the cause.
- While you are at it, inspect the neighboring parts of the assembly: they often wear out together.
