2. Description of the Related Art A vehicle is provided with various auxiliary lamps such as a fog lamp in addition to a main lamp such as a head lamp. For example, in the case of using a fog lamp used when fog is generated, a first auxiliary lamp that obtains a spot light distribution and a second auxiliary lamp that obtains a flat light distribution are installed on the front of the vehicle body. Thus, when traveling at low speed, the second auxiliary lamp illuminating the near area is turned on, and when traveling at high speed, the first auxiliary lamp illuminating the distant area is turned on. When the fog is heavy, only the second auxiliary lamp is turned on regardless of the vehicle speed (see Japanese Utility Model Laid-Open No. 2-92343 as a similar technique).

[0003]

However, in such a conventional technique, since the second auxiliary lamp for illuminating the near area and the first auxiliary lamp for illuminating the distant area are manually switched, the thinning is difficult. In the fog, switching is forgotten or switching timing is shifted, so that not only a light distribution suitable for the vehicle speed is not obtained, but also dazzling may be given to other vehicles.

The present invention has been made by paying attention to such a conventional technique, and provides an auxiliary lamp lighting control device for a vehicle which can prevent forgetting to switch or the like.
