Auto Dipping System

In an DUMPER headlight a 'meeting' beam (dip beam) is provided in addition to the driving beam (high beam) so as to reduce the dazzle for those approaching head-on to the vehicle. The Auto Dipping Device for a head light is intended to automatically change the Headlight Circuit to either driving beam or dip beam given a particular set of road conditions without the intervention of the driver. The present practice is to operate the dip switch manually.
The function of the headlight is to illuminate the road ahead of the automobile so as to reveal objects ahead from a safe distance; at the same time it should cause minimum discomfort and glare for drivers coming from the opposite side. The most extensively used and universally accepted anti-dazzle arrangement is the bifocal or double filament bulb. These bulbs have two filaments in which one filament is positioned in relation to the reflector to give the main forward beam while the other filament gives the dipped beam. The driver controls this system; either by a foot operated switch or by a switch mounted on the steering column.

An auto dipper could play a crucial role in shifting the headlights from driving beam to meeting beam and vice versa. This will improve visibility by minimizing glare a major cause of momentary loss of vision. The realization of the ultimate goal of total road safety through creating ideal visibility conditions is dependent on efforts in all other related areas mentioned above.
