<p>PURPOSE:To prevent the occurrence of lighting due to devilment by a method wherein, in a device which turns ON a main source through radio communication between a portable key and a transmitter receiver on the vehicle side, when a parking switch is operated, a lighting body, e.g. a parking lamp, can be lighted ON through radio communication. CONSTITUTION:In a motor bicycle, when a parking lamp 29 is lighted ON, by pressing a parking switch 3c on a main board 3 mounted to the central part of a handle, a request signal of a given frequency from a transmitting receiving unit 6 on the vehicle side is transmitted for a given period along with press of the parking switch. When the request signal is received by a transmitter receiver 7 carried by a user, a memory code signal intrinsic to the user is automatically transmitted the given number of times from the transmitter receiver 7. The memory code signal is received by the transmitting receiving unit 6 and compared and collated to a set code. Only when the two codes coincide with each other, a park relay 28 is energized to light ON the parking lamp 29.</p> |
