<p><P>PROBLEM TO BE SOLVED: To provide a lamp control device for a vehicle capable of reducing voltage supplied to a lamp with a simple configuration. <P>SOLUTION: A switch element T1 is arranged between a ground side terminal of tail lamps 14R and 14L and brake lamps 15R and 15L, and the ground, and the voltage supplied to the respective lamps is reduced by performing PWM control on the switch element T1 in the desired duty ratio. Thus, even when output voltage of a battery VB changes, the voltage higher than usual can be prevented from being supplied to the lamps, and the occurrence of the problem of shortening the service life of the lamps can be avoided. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
