<p>PURPOSE:To inhibit the lighting of a stop lamp at the time of operating a cold start switch. CONSTITUTION:Using a diode 30 allowing only the flow of a current to the exhaust brake actuating magnet valve 31 side from an exhaust brake switch 29, a stop lamp and the diode 30 are placed in parallel and connected to the exhaust brake switch 29. At the time of operating the exhaust brake switch 29, the stop lamp is lighted, and at the time of actuating the exhaust brake actuating magnet valve 31 by the operation of only a cold start switch 33, the lighting of the stop lamp is inhibited. In the case of operating the cold start switch 33, the lighting of the stop lamp at the time of operating the cold start switch 33 is inhibited with extremely simple constitution so that the stop lamp is not lighted.</p> |
