Abstract
A lighting device for illuminating operation switches installed on a steering wheel inlcudes a light-emitting diode and an instrument light. The light-emitting diode is turned on by means of a constant-voltage generator which is connected to a power source via a light switch to apply voltage that is less than a predetermined value to said light-emitting diode via a slip ring in response to turning ON of the light switch. The instrument light is connected to the power source via the light switch and is turned on in response to turning ON of the light switch.
