Abstract

PURPOSE:To enable the front of a curved path to be illuminated with sufficient brightness in travelling for ensuring safe travelling by detecting curved travelling of a car body and supplying current to a filament for travelling beams according to the detecting signal. CONSTITUTION:When a vehicle turns right for example, mercury 8 in an outer shell 3 of an inertia switch 2 is moved from the central lowered portion to the left side by inertia to electrically connect a side contact 6 to a central one 4. An auxiliary circuit AS.C is constituted by using such inertia switch 2 for a curved travelling sensor I.S. When a change-over switch D.SW is closed to the contact PC.S side for example and a filament S for beams of opposed vehicle is lit, the sensor I.S detects curved travelling and closes its contact so that a filament M for travelling beam receives current through a resistance R and is lit with reduced light.
