A vehicle, such as a motorcycle, can include an engine and a head pipe provided ahead of the engine. Electrical equipment provided behind the head pipe and ahead of the engine can be partly exposed by a gap between a down frame and a radiator of the vehicle, enabling the electrical equipment to be cooled by airflow.

Vehicle with electric equipment

A voltage adjusting circuit prevents damage to an electrical component having no over-voltage protecting circuit when a battery is removed. An LED tail light is connected to an over-voltage protecting circuit of a CDI unit. Electric power is supplied from a power supply control section to the CDI unit and is also supplied to the LED tail light through the over-voltage protecting circuit. Thereby, the over-voltage protecting circuit of the CDI unit protects the LED tail light from an over-voltage condition.
