<p>PURPOSE:To enable a lamp to be always lighted ON and OFF at an accurate point of time throughout the year, by a method wherein a date is detected by using a calender clock, and a lighting-ON and a lighting-OFF time are automatically corrected in a manner to match a change in a sun set time and a sun rise time due to a change of season. CONSTITUTION:A CPU 4 is provided for controlling lighting of head lamp H and a small lamp S of an automobile, and output signals from a lamp control switch 6, a car speed sensor 7, and a wiper circuit 8 are inputted thereto. A lighting ON and OFF time set means 3 is provided for storing a date, a lighting ON time, and a lighting OFF time when the lighting ON and the lighting OFF time of an arbitrary data are set at the date by means of a calender clock 2 and a user. In the CPU 4, correction on the lighting ON and a lighting OFF time is made according to a season, and when the small lamp S is lighted ON when it comes to a given time slightly earlier than a set lighting ON time at a current data, and the head lamp H is lighted ON at the lighting ON time.</p> |
