<p>A flasher device includes a printed circuit board enclosed in a casing, a B-terminal connected to a battery, an L-terminal connected to a direction indicating lamp, and an E-terminal connected to ground. A fixed contact of a relay section is attached to the L-terminal and a current detecting resistor is connected between the B-terminal and a movable contact of the relay section, so that a main lamp current flows from the battery to the lamp through the B-terminal, the current detecting resistor, the relay contacts and the L-terminal, thus avoiding the flow of main lamp current through copper foils formed on the printed circuit board.</p> |
