Abstract

PURPOSE: To increase the safety at the lamp breaking without dazzling the driver of a car running in opposite direction by lightenning an upper filament when a lower filament is broken and modifying the head lamp direction from an upward condition to a downward condition.
CONSTITUTION: When at least one of the lower filaments FLL, FLR is broken, a contact of a relay RE1 is turned on so as to latch the relay RE1 by a latch circuit LT, thereby turning on a transistor Q. Thus, the relay RE2 is energized to switch a contact HD to the H side so as to light the upper filaments FHL, FHR. At the same time, relays RAL, RAR are energized simultaneously, a contact CO is switched from a contact DW to a contact VP, motors ML, MR are rotated, and the head lamps LL, LR are gradually rotated in the downward direction. In this instance, since a contact AR is short and therefore the rotation period of the motors ML, MR is also short, the head lamps are stopped rotation when they are orientated slightly downwards.
